Prius (2004-09) :: 2005 - AC Malfunction / Possible Blockage Or Really The Compressor?

It's one of those days again when the temps are starting to get hot here in Austin, Tx. My AC started acting up during the Spring and first started working fine then after about 10-15 minutes of driving the air starts to blow warmer. The air doesn't go back to cold unless the car has been parked and off for several hours or overnight, and even after that it only blows cold for 10-15 mins again.

Well, I didn't have the time/money to mess with it. The recent May it stopped cooling completely. I recently took it to a local shop and we look at it together. Drained the system and the mechanic was saying it's pulling some air and a little refrigerant. Well, we recharged the system and we could only put in 0.5 lbs and the Low side just maxes out. The system is supposed to hold 1.06 lbs so we were left scratching our heads.

Decided to check for leaks, discharged the system again and hooked up a vacuum pump and see if the gauges will go below 0 for negative pressure and they never did. So the shop doesn't think my system has a leak. They could have used a dye to check but didn't have any on the shelf at that moment.

I also have a DTC code of B1476 and we followed the shop manual. Fans blow into the engine and sometimes we had the bubble but couldn't add more refrigerant due to the Low side being maxed.

My father thinks I most likely have a blockage somewhere in the system. If so, how I can check for this? Is there a specific place or two I can look to find out the system is blocked?

Some people on the form seem to have AC problems, including some with the B1476, and others that couldn't find the problem very well. I'm worried that replacing the compressor wouldn't solve the problem, especially if there is a blockage or something. I usually do a lot of mechanic work but I've never actually worked on an AC system before. I would love to dive into this, even if I can only do part of it and then send it to the Toyota dealer for a flush and charge.

Prius (2004-09) :: 2005 - AC Won't Working When Stopped For Short While / Replace Compressor?

I have an issue with the air conditioner of my prius. It just works while I am driving, but it does not work when I stop for a short while, such as waiting for signal. The fan is working fine. I visited a dealer and they told me the gas is leaking... but, they are wrong. I cannot believe them. The gas is fine and there is no leak and no problem exists at any other parts. Need to know about it? Should I replace the compressor?

Prius (Gen 2) :: 2005 - After Replacing 12V, Install Correct Map DVD Appeared

Recently had HV battery replaced by dealer in my 2005 with 129k.

2 days later the 12v went dead. I removed and replaced it, no problem except when I tried to go to my nav the screen said "please install correct map dvd".

I have never had a problem with my nav since buying the car new in 2005. I assume the problem is connected to the loss of 12v power. The player is under the pass seat.

Ford F-150 (2004-2008) :: 2005 - A/C Compressor Not Working

Truck has the EATC system. Blower motor works, blowing 78.5 degrees at the vent. Compressor will not kick on at all. I checked all fuses and they are good. Put gauges on the low and high side, both sides register a constant 70psi, held for 30 minutes with the a/c on max. What the problem is?

Lexus GX 2004-09 :: 2005 GX470 Suspension - No Compressor Activity

I have a 05 gx470 and I was having trouble with the rear staying bottomed out and not pumping up. I replaced both ride height sensors. Nothing changed until about 1 hour of driving the compressor kicked on. it road better but still bottomed out some. So I raised the sensors about 5mm. it road great for about 10 miles then went back to riding on the axles. No compressor activity. Also when the compressor is not engaging the push buttons do nothing with changing the dash from H-N-L no matter when you push it. If you hear the compressor running all the buttons will work just fine. I have a useless car because it is not safe to drive when its riding on the axle bump stops.

Prius (Gen 2) :: 2005 - AC Compressor Replaced 3 Times With New Toyota Parts In 6 Months

The 2005 Prius I bought has had the AC compressor replaced 3 times in about 6 months with new toyota parts, the repair shop told the man I bought the car from not to bring it back there anymore they cant find the problem and toyota will not replace the compressor again for free...I guess 2 replacements is their limit.

The AC blows warm and Im not sure how to tell if the compressor is working or not, the inside fan works on all speeds, the fan by the radiator comes on but is VERY loud....of course I don't leave it on, only for testing to try to find the problem.

Where to look or why this car is burning up compressors.

Prius (2004-09) :: How To Install Front License Plate

had a couple questions about installing the front license plate. I currently do not have any holes drilled in the front bumper (though I can see the places where they are supposed to go). I have the black plastic attachment. What is the best way to drill those holes? Can it be done if I don't have a drill (i.e., just with a screwdriver and force)? Is this something the dealer might do for free (I don't have a warranty, bought my car used)?

Prius (2004-09) :: License Plate Light Comes On When Any Door Opens Post Led Install

License plate light comes on when any door opens? it fades out a little after it's shut. stays on for a minute or so. (like interior lights would if i had the door dome switch on).

Any way to turn this license plate light off for this function? stays on if the hatch is open, or any door. I car camp a lot and crack the hatch for air. license plate light stays on.

Also the lower door lights, when they are individually open. I'd like them to not come on. Yes I could just remove those bulbs.

I had installed led lights on the whole car/ every bulb inside and out. even fog lights. i didn't replace the hid headlights, though I'd like to.

Prius (2004-09) :: Compressor Went Out Because Of Putting In The Wrong Oil

I have a 2008 Prius. In 2009, I got into a collision, and the car required extensive body work. This week, I took my car to the mechanic to repair the air conditioning system - only warm air was blowing out. According to my mechanic, the compressor went out because the auto body shop put in the wrong oil in the air conditioning system and re-installed the fans backwards. I got my car back today, and the air conditioning works really great!

However, my family spoke to their mechanic (different person from my mechanic), and he indicated that used compressors are dangerous due to the high likelihood that contaminants will be leaked. This sounds completely ludicrous to me. My mechanic said that the other mechanic's concerns are unfounded.

Prius (2004-09) :: AC Can't Take The Heat / Compressor Conks Out

The AC on my 2002 Prius works fine, as long as it's cool outside and I'm running it on low. As soon as I stress the system -- either it's above 75 degrees outside, or I'm running it on maximum, or driving on the highway for more than 30 minutes -- the compressor conks out. Fan's still blowing, but no cold air. The light on the a/c button starts flashing. If I turn it off for a few seconds, the cold air comes on again, but usually only for a few minutes, and then we repeat the cycle. The Toyota mechanics claimed they couldn't replicate the problem, but I bet if I forced them to ride with me up and down the highway on a 90-degree day with the windows up and no a/c, they'd believe me.

Prius (2004-09) :: AC Compressor And Condenser Cooling Fan Will Not Come On

I have an 05 Prius with 53k miles and the ac just recently stopped working. The blower fan still comes on, but neither the compressor nor condenser cooling fan will come on. I've checked the fuses and relays, and they check out ok. I'm hoping there may be one I missed? It just stopped working with no warning signs. What could be causing this? If the compressor was bad, the condenser fan would still work, right? I'm fearing it's the ac inverter. Do the symptoms match?

Prius (2004-09) :: AC Compressor Noise When Braking

Quick back story, bought the car a year ago, seller told me it was in an accident and the radiator was replaced. He let me know that the discharge AC hose was missing and that the other hose was disconnected. I also noticed that the low pressure cap is missing. I recently ordered and installed the discharge hose with the intention of filling the system later.

I have always noticed a noise/vibration coming from the passenger side when braking at low speeds. I havent noticed at higher speeds but maybe there is more road noise. The best I can describe the noise is that is sounds like a compressor running. I have a hunch it's the AC compressor and might be related to the regenerative braking, but I am no expert.

Prius (2004-09) :: 2006 - Air Conditioning Compressor Broke

I just found out that the air conditioning compressor is broke in my 2006 prius and its going to cost $1800 to fix it.. I am not in the loop here but that seems ridiculously high. I mean i save money at the pump but all that money just went out the door if i get this repaired. I am really contemplating trading the car in rather than deal with that expense..

Prius (2004-09) :: Disable A/C Compressor When Front Defrost Is On

a while back I had found and bookmarked a page here with info on how the dealer could program the A/C compressor to not be forced on when the front windshield defrost is on; but the page is now missing.

I want to disable the compressor being on during defog because it causes the air to be extremely dry and causes severe problems with my asthma; and as soon as I turn it off or switch to normal foot/front vents, all the water that had condensed on the A/C coil then spews out and fogs up the entire car badly. It's a vicious cycle that is dangerous.

Prius (2004-09) :: A/C Compressor Cycles On For Couple Seconds Then Stops

Just rescued this 2004 from a driveway death. While checking out a no A/C condition I notice that the A/C compressor cycles on for about 10-15 seconds then stops, does this 4 times and then ends. System shows low pressure but doesn't run long enough to build up any. Need to get the OBD-2 tester on it.

Prius (2004-09) :: A/C Compressor Out And ABS Actuator Failing After Hybrid Battery Replacement

A few weeks ago, I received the triangle light in my 2007 Prius with 125k miles on it. When I took it to the dealer, they said that the hybrid battery needed to be replaced. A new battery was ordered & installed by the dealer, which took a couple weeks as the battery wasn't in stock. When I picked up the Prius this week, within driving it a couple miles, it was apparent the A/C wasn't working. I took it right back to the dealer who said they'd look into it. When the Service sales guy started it again, it made a very strange noise as well, which it never did before. The dealer has come back and said that not only has the A/C Compressor out but the ABS actuator is also failing. They are saying this has nothing to do with the battery replacement but both these items were working fine before having the battery replaced

Prius (2004-09) :: Electric Whirring Sound When AC Compressor Starts Running

I have a 2009 Prius with about 56K miles on it that I absolutely love. Now I know from reading in the forums an my own experience that when the A/C compressor starts running you hear an electric whirring sound. My question is... is it a cause for concern when the sound it makes seems different -- the pitch sounds lower to me now. The A/C still works fine, but I didn't know if this changing sound means the compressor was on the way out.
