Ford Super Duty (1999-2016) :: 2007 E450 - AC Compressor Constantly Cycling
I have a 2007 Ford E450 Superduty Box truck with a V10 and 70,000 miles. For the 6 years I have owned it, the AC has always been ice cold. This summer it will not blow cold under any driving situation.
When the AC is on AC, AC max, or defrost, the compressor clutch constantly engages for 1.5 seconds then disengages for 5 seconds. I bought a can of refrigerant and added only about 1/4 of it to reach proper psi for the current temperature.
If I remove either the high or low pressure switch clips, the compressor stops engaging. Is it possible that one of the switches has failed in that it is activating at an incorrect pressure? Unfortunately our local Ford dealer here is notoriously devious and while they may fix the problem, I will probably have an entirely new system by the time they are done.
I've ruled out coolant, air gap does not seem to apply and both hi and low pressure switches are active. What am I missing?
Prius (2004-09) :: 2008 - ICE Short Cycling At Stoplight?
My 2008 did a strange thing last night -- the ICE was short cycling at a stoplight. It would start and then immediately turn off, then immediately start again. It did this about 5 cycles. Cold night, coldish engine, heater on, recent repair from being rear-ended (5 days since got it back from body shop). 12V battery seems good (12.3 volts no load, car not in ready mode; 11.6V withheadlights on and car off). No purpose could be served by such short cycles. We turned off heater and then the light changed and we were rolling forward and engine short cycled one more time and then the behavior stopped for the rest of the trip.

I bought this car new in 2010 and it's a level IV not Four as it is a 2010. I am about to replace my headlights for the 5th time after only having had these for about 3-4 months. The dealership says that things happen but I've never owned a vehicle where the headlights are constantly going out. The first 3 times that the headlights went out, the dealership replaced them. I replaced them this last time .
I don't believe it's the headlights as much as I feel that it has something to do with the car. They went out last night as I got into the car at night and when I switched on the lights, they flashed and went out. The high beams still work but the lows do not.
Prius (Gen 1) :: Fuel Gauge Blinking On And Off Constantly
I have a 2002 Prius with 143,000 miles on it. All bars on the fuel gauge blink on and off constantly, the seat belt reminder, open door warning, and headlight indicator do not work. I checked all fuses & load tested the battery.

Our Prius is a second generation from 2006. Over the weekend the right front hub bearing was replaced. This was their diagnosis after we reported hearing "humming" noise from the front side of the car. They did a test drive around the block and they said that this was the problem. True enough, the noise went away after they have done the procedure. Unfortunately, the ! ABS VSC lights are now constantly on. I noticed this when I drove the car going home (about a mile away). I reset the jumper pins 4 and 13 on the DLC together with pumping the brake pedals.
This immediately solved the problem with the lights. They were off now and everything was back to normal. I then did a test drive, and lo and behold, when I hit on the brakes, no matter how soft, the car jerks as if the ABS was engaging. This happened twice before the ! ABS and VSC lights again went off. As soon as the error lights went back on, braking became normal once more - no more jerky and intermittent braking.
I then drove home and did the jumper procedure again to make sure that the first attempt wasn't just a fluke. I had the same experience as before, car braking became intermittent and jerky. The ! ABS and VSC lights again turned on - and right after, braking became normal.

I am on my 3rd set of wiper blades trying to get rid of the skipping motion. I did not notice this problem with original. I bought one set at Autozone that skipped, went back and bought an expensive pair of blades, they skipped.
I bought the best wipers t, they skipped.
I just went to the dealer and got a pair of blades, they skip just as bad as all the others I've tried.
I have tried cleaning the windshield, This last time I used clay bar on the windshield but that made it worst. It would skip after each swipe after I used clay bar.
The last thing I done was use some waterless wash on windshield that has it temporally stopped skipping. The wipers run smooth so there is not a problem with any jerking or motion or anything like that.
I have 115K on 2011 Prius, not had a minute trouble out of it except for this skipping. I also have about 65K mile on this set of Michelin Energy saver A/S tires, they will go another 10K. I'm averaging 51 mpg Summer and Winter.

View 19 RepliesPrius (Gen 2) :: TPMS Warning Light Comes On And Staying On Constantly - Reset?
I have a bad sensor in a tire that just had a flat. I have ordered the sensor for the wheel and I am wondering after I install the sensor in the tire will the 'reader' pick it up and reset itself or do I need to go through the programming of the new sensor? At this time the TPMS warning light comes on and flashes for a minute or so before staying on constantly. This tells me it's trying to read the tire sensors but there is a fault, which is the tire sensor where I just had the flat. Costco tells me that sensor reads 78psi, which is incorrect. The fact that the reader is trying to read all the sensors and getting an error makes me think that it might reset itself when the new sensor transmitter is put in the tire? Any chance of this resetting itself or will I need to reprogram the receiver unit?

The past week I have noticed my battery cooling fan running constantly on all highway trips - 20 mile one-way trips going 65-70MPH.
The performance of the battery doesn't seem be degraded, but it seems like the battery is hopping more between charging cycle or whatever you would call it , where you watch the instantaneous MPG on the highway drop down for 10 seconds to 40-50, then back up to 60-70.
The car is a 2011 Prius III. It did not run like this earlier in the summer in the same weather conditions, I would hear the fan maybe once every few weeks in hot 90 degree weather. Now I hear it constantly. This is my first summer owning the Prius so this may be normal, but I wanted to double check with you all if this is a sign of premature traction battery death or something.

I think it is defected.. they don't want to admit it and replace for me.
Prius (2004-09) :: Vacuum Pump Running Constantly And Rattling?
I had the doors open while unloading the car this morning and noticed that the brake booster pump just kept running and running and running, plus I can hear a strange, hollow rattling sound somewhere under the car that coincides with the pump. When I say it runs "constantly," I really mean that it runs for 10 seconds (with the rattle), stops for about 5 seconds (silence), runs and rattles for ten seconds again, stops for another five, and just keeps on going for as long as I care to sit there with the door open.

My 2005 Prius, 88K miles, has developed an odd quirk. For about a month, the AC will not retain the last temperature setting. For example, you drive the car, set the temperature to max cold, arrive at your destination, turn the car off and when you start it again the temperature has reset to 75 degrees. Never used to do this before. I'm hoping it is just a module of some sort and not a major AC repair.

Got into my car this morning turned on the car and the hazard lights started to blink . Thought I might have pressed the hazard lights button , so of course I press the button into the lower position and the lights are still on .. Then I press the button again into the raised position and put the car into drive and now the hazard lights start to blink faster as I accelerate ( now my Prius Became a police cruiser ) it's obvious I have a short some where , or the relay went bad . If it's the relay, where can I find the relay in the car? Looked in both fuse boxes and I couldn't find it . I've since pulled the fuse on the hazard/ signal lights. I'd rather try to fix this my self before I have to pay Toyota to rob me blind .
