Golf IV / Jetta IV :: No AC After Running For Few Seconds But Compressor Engages?
Weird A/C issue that started yesterday. Had ac on all morning, start my car after lunch, a/c runs for a few seconds, hear a squeak (like a belt sticking) no more a/c. Moving the temp knob makes no change just all hot air. Both fans engage, compressor and what I believe is the clutch engage, hoses get cold, and no CEL's. Really stumped here.

I just put new rear air shocks on my Buick Lucerne. I noticed the back in my car bounced more than once when I tested them. After starting the car I hear the air compressor run for about five seconds. This seems to have no effect on my new shocks. The old shocks had holes in the bladder. What tests can I perform to figure out what's wrong?
View 8 RepliesFord A/C :: Compressor Cycles On For 18 - 25 Seconds / Cool Air Blowing
In my 08 Expedition I notice the a/c compressor cycles on for 18-25 sec. then off for about the same. This is with an ambient temp of about 75f. A/C seems to be blowing cool air-never was really cold since new. The idle drops/surges a bit when the a/c kicks on also-which is what grabbed my attention. Is this a normal or is it short cycling?
View 1 RepliesPrius (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.
View 1 RepliesChevrolet - Equinox :: A/C Not Working When Car Stopped / Compressor Only Turns On For A Few Seconds
I have a 2008 Chevy Equinox, and have had issues with the air conditioner for a while (see my other post: [URL] ....).
Lately, if the car is stopped in traffic or at a red light, I cannot get any cold air. The compressor will turn on, but only 2-3 seconds, then it shuts back off. It will cycle like this, on and off, about every 10-15 seconds while I am stopped. Each time this happens, the RPMs jump and the car lurches forward a little as well. As soon as I start moving at a decent speed (20 mph or so), the air gets cold again.
The recommendation from my other thread was to replace the heater control module.
Ford Ranger / B-Series :: AC Compressor Engages Then Disengages About Every 5 Seconds
I've got a problem with my AC Compressor, with the AC on the compressor engages then disengages about every 5 seconds. Now I looked into it and some people said you can remove a washer to remove a gap. Do you think I should change the whole unit? Looked online and I can get one for $100. If I do work on the AC compressor to try and fix it or remove the whole unit do I need to drain any refrigerant etc etc. I have a hayness repair booklet and they said that to remove the ac compressor you need to get it drained by professionals. Although on the compressor I only see a electrical plug and no hoses.
View 14 RepliesCamry :: 2002 - AC Compressor / Belt Started Squealing For A Few Seconds Then Stopped
I have a problem with my A/C Compressor. The other day while going down the freeway my belt started squealing for a few seconds then stopped. Yesterday when my wife was driving it did it again, and then another time while at idle and the engine struggled and almost died.
I went to look at it last night thinking maybe the belt was loose, but what i found was when the A/C Tried to engage, you here the click, and you see the compressor clutch jolt but not spin. It tries to engage 3-4 times before the system stops and the ac light blinks. Also found some burnt belt on the clutch pully. To me it sounds like the Compressor is locked up or frozen somehow inside.
My first instinct is to get a new compressor. Ive done a bit of mechanic work but not much on A/C. If i replace the compressor, do i just have a shop vac it out, replace, and recharge? car has 150,000 miles, do i need to replace any other components? 2002 V6 Camry....
Ford 6.7L Power Stroke Diesel :: Compressor Kept Running For A Few Seconds After Truck Was Off
Strange thing happened yesterday and again today. I have my compressor hooked up to up fitter #3 ,turned it on yesterday to fill the tank back up to 120psi. Before it filled up i shut the truck off to fuel up..but the compressor kept running for a few seconds after the truck was off. and today doing some running around the compressor turned on out of the blue when i was driving..but the switch was off.
The shut off switch (on the compressor itself) turns it on at around 90psi and shuts off at 120, but the thing filled my tank to 180 before i noticed it was on, pulled over to shut the truck off and again it ran for 10-15 seconds after the truck was off. I'm pretty confused. maybe it has something to do with the build up of snow under the truck, we just got 16" two days ago. but still when the up fitter is off shouldn't that cut the power from the accessory hooked up to it?
Sierra :: 2000 5.3 Sierra Suddenly Overheated In Cold Weather Then Fine
A friend of mine has had this 2000 Sierra since new. It has just over 100K and never had any cooling issues before. Last week when it was about 10 below zero she drove it home and it overheated and pumped a couple quarts of antifreeze overboard.
She refilled it the next day and it was fine but got it looked at by a local independent mechanic. I had told her that it was likely a sticky thermostat and it ought to be changed out anyways due to its age. The mechanic thought I was wrong and that she had driven it off to quickly in the super cold weather.
Ford 7.3L Power Stroke (1999-2003) :: Compressor Clicking On / Off About Every 5 Seconds - Clutch Smell
On 2500 mile trip, no A/C last 400 miles and we're cooking
Compressor clicking on/off about every 5 secs, clutch smell. Seems to be turning okay.
I brought some tools, including a full socket set.
Can I pull the clutch and remove shims in the campground? Looking for a condensed version of how?
Worst case, how do I replace the clutch- of I can find a dealer with one?
Pulley and clutch fixed, but cycling on and off...adding freon?
Ford A/C :: 2006 - Air Condition Went Out / Compressor Turns On Runs For A Few Seconds And Then Turns Off
I have a 2006 Expedition with 90k miles. I am the original owner. don't drive the vehicle much just mostly when the family goes somewhere or when I'm putting the Jet skis in the lake.
About a year ago the air con went out and since I don't drive it that much I decided to fix it later, well now is later. How to diagnose the AC system. what I am looking for is a methodical step by step procedure for trying to find out what is causing my AC to not work.
the symptoms are, the compressor turns on runs for a few seconds and then turns off. inside the cab I can hear hear a hiss noise during the few seconds that the compressor comes on and fades away slowly when the compressor shuts off.
I bought a can of 134a with the gauge, I adjusted the gauge for the correct ambient temperature hooked up to the low side and was surprised to see that the Freon was only a little low. I topped it off but still no change in the compressor running.
I bought a set of manifold gauges from Harbor Freight (I know I know you get what you pay for) in any case I hooked up the gauges to see what the pressures are when the compressor turns on but only seeing a little change.
Any way I took my Speedy (expedition) to the local auto air conditioner shop the mechanic hooked his gauge set up to the vehicle, watched it for a few minutes, made some phone calls, came back. He did tell me that he was going to have to replace the compressor, condenser, dryer, expansion valves both front and back and flush the rest of the parts that did not get replaced. I suppose this is a good price if all that work really needs to be done???
However I would like to exhaust all of my options before I dump half the vehicles blue book value into the air conditioning. so I've been searching the internet and found that it is possible the problem may reside in a control valve that may be present in the type of scroll compressor that is in the expedition.
Ford 7.3L Power Stroke (1999-2003) :: Fuel Pump Runs For 20 Seconds At Key On / Long Start Takes About 6 Seconds
This applies to a 2001 F-350 with 73,000 miles on the engine. Engine oil level is good, batteries charged, HPOP reservoir is full and passes Cody test with flying colors. Fuel pump runs for 20 seconds at key on. Start takes about 6 seconds. If I shut the key off and restart immediately it starts in under 2 seconds but if I wait about 30 seconds it's a 6 second start. Here is an AE that I ran on it, it has me stumped. FWIW it seems to start quicker when AE is hooked up. ?? An odd whir type of noise comes out from somewhere under the hood when I first turn the key on and when I clear the codes with AE.
View 14 RepliesHonda - Cr-v :: Radiator Fans Run For 5 Seconds And Then Off For 20 Seconds All The Time
My independent mechanic says my radiator fan and AC fan are cycling too much. The dealer says they are not. I know it started about 6 months ago and that I get 2 miles per gallon less now. If the heat, defrost selector is in any position it happens as long as the fan control in not on off.The fans run for 5 seconds and then are off for 20 seconds. The independent says the AC has refrigerant but doesn't know what is causing it. It happens at all outside temperatures. It happens at all car temperatures. (Just started, been driving for an hour etc.)

I just started having a problem with my 4wd.
When I push the button to select anything other than 2 hi, the indicator light for the selected range will flash for about 30 sec and then it reverts back to a steady light on the 2 hi button.
I have already replaced the pushbutton unit and nothing changed there.
How can I troubleshoot it from this point?

View 1 RepliesSierra :: 96 - AC Only Get Really Cold At Highway Speeds
I have a 96 Sierra with the 5.7L (R) engine. My a/c used to work fine...no problems. Then it started to only get really cold at highway speeds, plus you could also hear the compressor running (kind of making a clicking sound) when you push the a/c button to turn it on. I thought that the system needed to be recharged, so I bought a recharge bottle at Shucks that has a low pressure gauge on it.
It says that the low pressure port is the larger of the two and will only fit on the low pressure port, but it will only fit on the smaller port (right side port when looking at the compressor). With the a/c on max, the gauge reads 110, so I didn't try to recharge the system.
Then yesterday, my a/c won't even cool at highway speeds. It just blows warm air. The compressor is running (I can hear it, and the clutch turns). I disconnected the switch on the evaporator and the compressor stops, then restarts when I reconnect the switch.
Sierra :: Brake Lights Come On Then Immediately Go Out
The brake lights on my 97 GMC Sierra are not working right. When you apply the brakes the lights come on when you first press the pedal but then they immediately go out. I'm thinking brake pedal switch. Any other possibilities I should look at?

View 1 RepliesSierra :: 1991 SLE - Oil Pressure Fluctuates From Around 20 To 80
I just purchased a 91 sierra sle with the short bed. I am interested in buying a cap for it because the snap on tonneu cover is falling apart and id like a cap. Would caps from other full size short bed pickups work or does it have to be from a sierra/silverado?
Also i notice the oil pressure fluctuates from around 20 to 80 depending on if I am idle (20) to acceleration at 80, when driving it seems to go up and down to depending on the accelerator position. is this normal??
