I have a 98 Buick Regal. When my air conditioning works, it is beautiful. On a hot and sunny day when I pull out of the garage, I can run the air conditioning until the car is turned off. After reaching a destination and parking in the hot sun the compressor will not blow cold air. If the day is overcast or cool, the air conditioning works fine. What the problem might be?
View 4 RepliesThe horn on the vehicle is not working. The fuse and relay have both been tested and replaced. The horn itself does work when connected in an alternate method. Trying to find wiring from steering column to horn to determine issue. Any wiring diagram that shows color of horn wire from steering column and route it takes
View 1 RepliesMine is starting to leak. Watched a couple vids, they lifted the motor passenger side with a hoist and removed the bracket and mount, dogbones etc. That bracket had two bolts on one side and three on the other. They didn't unhook the exhaust or lower the frame either.
View 1 Replies1998 Buick Regal has strange readings on the gauges. 80-85 degree ambient air temp, low pressure is 60, high is 125. I have 100 lbs of static pressure in the system with the engine off. I am getting some cool air, but I would expect that the high side pressure is not high enough to cool well. Do I have a plugged orifice tube? Is my compressor not compressing enough? Or is my refrigerant low and causing the problems somehow?
View 13 Replies1998 buick regal gs. My problem is when i throw my turn signal on at a stop or coming to a stop the car completely shuts off. Also now I have the problem with when that occurs I try to start it and now it won't do anything! Then once started the brake light and the anti lock light with the trac light is on and wont let me move the gear shifter out of park!
View 5 RepliesI now have an annoying "clatter" sound coming from my supercharger cone housing ONLY when the car is in gear and at idle (i.e.,: stop light,etc.).. Had a new serpentine belt replaced 6 months ago with new water pump.114K miles, great condition otherwise.
View 1 RepliesThe backup lights don't work and a simple test shows the wires have no power. The bulbs test good. I also checked all the fuses and they are good. Where is the switch located? Also, I searched AutoZone online for the part and get no results.
View 4 RepliesI have a 1998 Buick Regal where the steering wheel randomly locks up while I am driving it. I usually stop the car and start it back up with success. The last time this happened was after I had the supercharge engine replaced. Once it locked up it I tried to start it up. The first time it did not restart, but the second attempt worked. I have taken it two really good mechanics and neither were able to diagnose the problem. I cannot remember if I am running the air conditioner when it happens. I know that sometimes I am. What could be causing my car to randomly lock up like this?

As the title says, when I start the engine cold I get a slight puttering and drop in RPMs followed by the engine revving itself to about 1100 for a few seconds and then normalizing at 600. It has only actually stalled out a few times. This does not happen once the engine is near operating temperature.
Now, I did not notice this issue prior to doing some maintenance on the vehicle (radiator replacement and transmission service) and I've read that this can be caused by a faulty coolant sensor. Possible?
Battery is new.
Also, when I say cold start I mean summer temps here in Michigan. So it's happening anywhere from 50 to 90 degrees F.

So here's an interesting observation. When i turn the ignition to ON, I hear no sound nor feel any vibration from the fuel pump. Is there any scenario where a fuel pump fails to prime yet kicks into gear after a start? So, I've got rough idles and misfires on cold starts. Before I start replacing parts my diagnostic plans is as follows:
Remove and inspect spark plugs.
Inspect and test starter coil/distributor (still have to research how to do this)
Test resistance on fuel injectors.
Test pressure drop on fuel rails.
Test compression for possible small head leak.
I'm wondering, if I do have a tiny head leak that is letting in a drip or two of coolant after hours of the engine sitting, will I be able to see this on the gauge doing a compression test? I've never done one before and still need to buy a gauge, but maybe I'm better off just doing the other tests and if they all check out I can be certain it is a minor head leak.
My assumption is that I have a leaking injector; just trying to do things the proper way.

Having a rough idle on a cold start. After some research and closer inspection of the vehicle, I'm quite certain I have at least one leaking injector that is flooding a cylinder and causing the car to misfire on a cold start. I'm also not at the gas mileage I should be at.
So I'm wondering, is fuel injector replacement as straightforward of a job as it looks? Any major issues I could run into in doing a replacement?
I'm planning on replacing all six injectors (I can get them for $50 each buying online with a discount code), but given that the vehicle is so old am I better off just replacing the faulty ones? I'm assuming pulling the spark plugs and seeing which cylinder is wet will tell me which I need to replace.
And one more question: Is there a way to depressurize the fuel system when I park the car for the night, thus preventing fuel (or most of it) from leaking into the engine until I get this fixed? I've read that just unscrewing the gas cap can depressurize the system.
Ok here is the issue, my girlfriend owns a MK4 '99 Jetta. Through the search I was able to figure out why she is having so many issues with her door locks and how they can be fixed on the cheap..thats awesome. But here is the problem. She was driving down the road the other day, A/C working...then suddenly it stopped blowing cold. Fan is still working, just blows hot air. She said it started blowing warm suddenly and hasnt been getting warmer through out the past days or anything.
With the hood popped and the a/c on, you can see that the compressor isnt engaging. The car makes a noise like its engaging the compressor, but nothing is happening that I can see visually. Seems as if the compressor is not getting the signal to engage. It sounds like its trying to make the compressor kick on about every 5 seconds or so. Basically that initial clicking sound that your hear RIGHT before the compressor comes on when its working normally.
We have checked the fuses and no luck with those, all look good. Seems like its an electrical issue to me. What this may be? Bad pressure switch? Low pressure in the system? I know the car has had the compressor replaced before...and the clutch seems to spin freely when the car is off.
I have a 2007 F150 with a 5.4. I am having an issue with my A/C and more.
Here are the symptoms:
1) A/C doesn't blow cold, at times.
2) Compressor not coming on, according to mechanic.
3) Engine sounds like a freight train, at times. Like on a super cold day and it has to work hard.
4) Very poor fuel mileage since this started.
I took it to a shop, and they said it was the engine cooling fan that would not come on. So I replaced it. Same issue. I then took it back and was told there is a wiring problem. After 3 days they couldn't find it. I needed my truck back and dropped it off again. Then they said it was the A/C compressor, maybe. They wanted to try it and then see what happened. I told them no way.
Temperature, according to the gauge is good. Noise comes and goes. Not dependent on anything. Weather, temperature, car heated up or dead cold. Just comes and goes.
Air conditioner was acting weird. (It doesn't blow cold air when the car stops at the lights or in the parking lots. But it works great while driving). Then I went to dealer. And they scan my computer. And they said we need to change Aux Fan control unit and also one of the fan .I ordered OEM Aux Fan Control Unit . And I installed it. I connected Vagcom and cleared the Fault code but It still acts same. I checked the fans. They both works fine to me. They run 10 seconds and stops. So I didn't get this part. How the heck this AC works fine while I am driving but it doesn't work when I stop ?
View 7 RepliesThe A/C does not blow cold. The Compressor clutch does kick on and stay on The passenger side fan kicks on only (I think the driver side is toast but i need to test it to confirm) The system has 45psi on the low side
I did not check the high side as I don't have a gauge for it but will get one if I need to test that. So my thoughts are that my expansion valve is toast which is what expands the hot liquid and turns it to cool liquid so the A/C gets cold. I think this because it seems all of the other components work.
I drive a 1996 Buick Park Avenue Ultra and my front dash blowers do not blow air (hot or cold). The defroster and the floor vents work fine, but not the front vents. I have heard this means something is wrong which has put my HVAC system in "default mode." Could this be a disconnected vaccum line somewhere and if so, where do I look for it? How do I troubleshoot this? I should also add that the electronic controls and display all seem fine. ParkAveUltra
View 7 RepliesI'm at the end of my rope! My 2005 Ford Five Hundred Limited has a constant problem with the A/C system and overheating. In the last year I've replaced the compress, expansion valve, dryer FOUR times. They have replaced the condenser, blower motor, and added Freon, and checked for leaks. It will blow cold when running fast and then blow hot. They have replaced belts pulleys, They have replaced the thermostat, fans, coolant reservoir, hoses. and it still overheats. I've taken it to 4 difference mechanics including two dealerships. No one can seem to fix this problem.
View 9 RepliesAbout the Car: It has 101,00 miles on it. I haven't own this car for long (less than a month). I bought it pretty cheap to do some grocery shopping with. I have no plans to drive it more than 10 miles in a trip. I have a bicycle with a trailer, but there are days in the winter when the weather says, "No" to bicycling. I had the fuel pump and filter replaced at a shop when it wouldn't start a couple weeks ago. They said the fuel pressure was low, and it needed to be replaced. It was fine for a little while, but then it wouldn't start for the past three days now. No cranking at all. I can turn on the radio and roll windows up and down, though. I do remember seeing a Check Engine, Battery symbol sign, and a couple other lights off-hand. I'm at work right now.. so I'll have to go home to see if the Security light also was there, too.
Also! I did find an electrical line that did not go anywhere... not sure if that has anything to do with the fact that there is no window washer fluid tank (wipers do work).
After reading a little about other Buicks in the forum not cranking, I will definitely try the Security Light issue after I get home from work.
My 97 regal has a noise from the compressor clutch. It goes away when the a/c is turned on. Mechanic said its the clutch assembly. Is this easy to change? What causes the noise to go away when the a/c is turned on?
View 6 RepliesI have a Buick regal 1996 v6 3.8l . SO my car tends to over heat really fast with the reservoir still nearly full of coolant also my fans also turn on really late.. Ive came down to the conclusion that it might be the temperature sensor idk whatelse to do. Ive changed the thermostat about a month ago.
View 14 RepliesI have a 1999 Buick Regal GS with a supercharged 3.8 liter engine and 161,000 miles. I bought the car off of my uncle and he said he would have to change plug wires every month to month and a half because it would start missing so bad. When I first drove the car it would quit on me at red lights and in parking lots, it only seemed to do it at low idle speeds. I live on a hill with a blacktop road and I had to give it a lot of gas just to pull the hill it was missing so bad. The plug wire had a lifetime warranty on them so I replaced them and it stopped quitting on me but I still had a bad miss at random but not as bad it would just be like hard jerks. I added sea foam fuel injection cleaner and had the fuel filter replaced. The mechanic checked the spark plugs and he said they were like new AC Delco. I also cleaned the MAF Sensor (the mechanic told me to and how) because the engine did not run steady at idle and it seemed to work that, but not the miss. Could my problem be the plug wires? They are carquest brand 7mm wires.
