Jeep - Cherokee :: Air Conditioner Does Not Always Blow Cold

I have a 1999 Jeep Cherokee and the air conditioner is giving me some problems. The issue is that at random times, it stops cooling, and just blows hot air. Sometimes I can drive all day, and it's fine. Other times, it only blows cold for a few minutes, before the air gets warm.

I've started checking under the hood when this happens, and the compressor is not engaged. I noticed a couple of times that the hoses were frosted over (not every time when the compressor was out). I have found that when the air starts blowing cold, I can turn on the heater for a few minutes, and then when I turn the A/C back on, it will blow cold air again. However, often times the cold air will only last around 10 minutes before it blows warm again. Plus, there are a couple of instances where the heater trick didn't really work.

Toyota - Sienna :: 2004 - Air Conditioner Only Blow Hot Air

I have an 8 year old 2004 Toyota Sienna LE minivan. This past weekend I tried running the air conditioner when the temperature was in the low 80's (F) outside. Unfortunately, the AC only blew hot air, even though I drove a pretty long distance with the AC on.

I think the refrigerant has leaked out and is depleted. Whether or not I should attempt to recharge the AC by myself with my neighbor's assistance (he has all of the gear for recharging the refrigerant) or if this is a job that is better left to a professional.

Also, if I do attempt the job by myself, would it be better to try and seal the leaks with a dedicated sealant first, or should I use the canned refrigerant that also contains some kind of sealant?

Camry :: 2007 - Air Conditioner Takes 5 Minutes To Blow Cold Air

I own a 2007 Camry LE. It's 4 cylinder and has 80k miles. Since I can remember, the A/C takes a really long time to start blowing cold air.

I'm in Miami, where ambient temp is about 90 F every day and it takes about 2-3 minutes to blow cold air. I can tell because this usually happens when I get around a certain street (SW 40th Street), so the problem is self-replicating regularly.

My father is a house A/C mechanic and he filled it with refrigerant but this has not fixed the problem. If the car has been driven and been parked under shade, the A/C blows cold air since the start. After being driven for 2-3 minutes, it blows cold air like a monster, I usually have to run it on 70 % cold and low fan - that's how well it performs.

Toyota - Prius :: 2007 - Air Conditioner Blows Mainly Warm Rather Than Cool Air

My 2007 Prius air conditioner blows mainly warm rather than cool air. I took it in for repairs and they replaced the high pressure hose but it is still not cooling the car. The dealer has had the car for 2 weeks trying to determine what the problem is. They tell me it should be blowing 42 degrees but is only blowing 62 degrees. They think that it might be the invertor that cost $1,000.

Chevrolet - Cavalier :: 2002 - Passenger Side Headlight Went Dim Suddenly

I have an '02 Chevy Cavalier whose passenger side headlight went dim suddenly one day when I started the car. When I start the car, the daytime running headlights indicator flashes and clicks, and then the service light comes on. I have tried the following:

1) Swapped light bulbs between the two lights. It is not the bulb.
2) Swapped fuses between the two lights. It is not the fuse.

Even stranger, when I remove the fuse to the dim headlight, the light stays on. My guess is that I have a short somewhere in the wiring. I took a brief look at the connection between the socket and the wiring and everything looks good there.

Intrepid :: 98 - Heater Will Not Blow Hot Air When Idling (just Warm)

I am having a problem with the heater on my 98 2.7 Intrepid. Will not blow hot air when idling (just warm). After several minutes of driving with heat on air temp goes from hot to warm. It might just be me, but it seems like the air flow is cooler coming out of the defrost vents than from the dash/floor vents. Thermostat has been replaced (proper operation verified before installing). Had to replace gooseneck and heater coil supply tubing due to a leaking bleed valve. There appears to be NO air in the system.

Heater core was backflushed, there appears to be no restriction. Hose temp on exit line is approx. 15 deg. cooler than supply line when fan is running. Blend door actuator was replaced last spring (motor shorted). When temp control is moved from hot to cold temp changes drastically and door can be heard moving. On-board ATC diagnostics indicate all is good. Engine is running at normal operating temperature, not overheating or running cold. Is there a cabin filter or inlet supply for the air that could possibly be obstructed? Air flow seems adequate, not restricted. AC works fine.

Suburban :: 2000 - Heater Blow Warm But Not Hot Air

I have a 2000 suburban with a 1500 motor and 300000 miles. Last year I replace the water pump and the thermostat. The heater would blow warm but not hot . But only when I start to drive. Yesterday I decide to change thermostat again thinking the new one from last year was faulty. Now the heater only blows cold air .

Prius (2004-09) :: Heater Won't Blow Warm Air

My heater quit blowing hot or warm air all of the sudden. I took my mechanic and they said it showed no codes and were afraid to mess with it so I took it to a dealership. They worked on it most of a day. Said nothing showed a code as bad, they got into it and found the air going into the heater core was hot, but it was cool coming out. They spent some time flushing the coolant and said they found some sediment in the coolant fluid. They were hoping to flush out anything clogging the heater core.

Passat (B7) :: AC On But Will Blow Warm Air When Start The Vehicle

Having issues with the AC system turning on to blow cold air? The problem seems to be intermittent so I don't know how I would be able to replicate the problem if/when I take the car in for service. My problem typically occurs when I start the vehicle. The AC will be on but will blow warm air. I seem to have to continually play with the HVAC controls for it to finally kick on and blow cold air.

When I searched, I read that the malfunction may be caused by a bad solder in the system but wasn't able to find a concrete resolution to the problem. Should I call a few dealerships to see if the service writers are aware of the issue? Being in AZ, not having AC for the first 5-10 minutes in the car can be brutal. The car in question is a 2014 3.6 SEL ...

Passat (B5) :: Temperature Suddenly Dropped, But Air Continued To Blow

It's been quite a while since I was here - which shows that my Passat has been pretty reliable recently. But now I have a problem. WHen I was driving home about a week ago, I saw the temperature suddenly drop all the way to the stop. I put on the heater, and the air continued to come out at regular temperature, so the problem was in the reading/display. I have a Scangauge, which I connected, and it showed the correct temperature (around 190), confirming a problem with the display.

I contacted the dealer, who first insisted that it must be the thermostat (then why do I get a reading of 190 with the Scan Gauge and why is the heater still hot). When I disagreed, they said it must be the sensor. When I pointed out that the Scan Gauge correctly shows the rise in temperature for cold and then show the temperature maintained at between about 185 and 195) , then they said it must be the gauge, which requires a new instrument cluster.

I went to a another service place I've used (not a dealer) and they insist that it must be the sensor, based on past experience. For this to be true, the engine must have different temperature sensors for the instrument cluster display than it does for the computer.

Isuzu - Rodeo :: 2000 - AC Blow Cold Then Warm On Sunny Day

I have a 2000 Isuzu Rodeo with 230,000 miles. The A/C is cold when first turned on after start up, warm or cold engine. After about 5-8 minutes running on a sunny day, driving or at a stop, it starts blowing warm. If I shut the A/C off and leave it off for 30-45 seconds, it will blow cold again. On an overcast day it will blow cold for 15 minutes or more.
