Airconditioning :: 2008 Pontiac GT - AC Only Works When Coolant Shows Reading
Jun 25, 2014
I have a 2008 Pontiac GT, regularly maintained and all runs fine. Just one problem that has popped up over the last few weeks since the warmer weather has arrived: On the computer readout in the dash, if the "Coolant" display shows a temperature (say, 83C or what have you), then the AC works. However, much of the time the Coolant reading shows "---" (3 blank dashes), and the AC does not work. It's still been quite cool around here (Toronto area) so I haven't needed the AC much but it's heating up and I'd sure love to take care of this if possible.

My AC is not working on any setting but defrost. Warm air blows out on the reg AC settings, but if I turn it to defrost, chilly air comes out.

2004 Chevrolet Tahoe that has the dual climate control features. Some days the A/C blows cold on one side and hot on the other with it set on the coldest setting. Another day it blows cold on both. Then you guessed it a few days later it goes back to blowing hot on one side and cold on the other.

The 2007 Prius starts and runs fine with no problem. However, the 12v battery check with a multimeter shows 9.9v reading. Does this mean that the 12v Battery is coming to end of life and needs to be replaced.

I've got a 2001 Volkswagen Jetta 1.8T Wolfsburg Edition.
Recently the temp gauge sits at 260* as soon as the car starts, but it's not actually overheating. Car runs/drives fine and will do so for many, many miles. Even in stop and go traffic. Was told the thermostat was replaced, but that didn't fix the issue although it doesn't sound like a thermostat issue since the car isn't actually overheating. Coolant is topped off as well.
I am thinking it's a bad sensor. Where is it located on this car?
Car is a friends and she said she took it to a shop to have the coolant checked and they were also the ones who did the thermostat.

I have a 2006 Chevy Colorado, 5 cylinder, automatic, 4wheel drive with 62,700mi. 1st problem occurred in 2013 new thermostat was replaced then in 2015 temp. gauge shows overheating problem again. All diagnostic problems have been analyzed by mechanic and nothing further could be done. Mechanic suggests to take truck to dealer. The temp. reading still shows above normal operation and the engine compartment has signs of overheating also. If the truck driven on uphill range the temp. goes higher I refuse to drive in this condition which will surely ruin the entire engine.

I just bought a 06 F250 King Ranch and the information center on the gauge cluster just shows the current odometer reading. When I press the information button that is supposed to toggle between trip mileage and avg mpg just the odometer shows. This truck was vandalized (bought from auction) so I am wondering does it have a XL cluster so I am asking are all the clusters different between XL, XLT, Lariat, King Ranch, etc and I have the wrong one installed or maybe there is an issues with my information center.

I have a 2004 rx330 and it's recently been acting up. Sometimes the heat and air won't work, there is a noticeable difference in the way the car drives too.
I hit climate and it shows check air conditioner connection line and nothing works, it's making for very cold drives to and from work.

I just picked up an 05 6.0 Limited and love it, but I can't figure out the overhead temperature gauge. It shows -40 degrees no matter what, but if I hit the outside temp button on the climate control, it shows the (mostly) correct temp. I verified that the temp sensor in front of the radiator is still there and hooked up, and it seems to me that Ford wouldn't go to the expense of using separate sensors for each readout, so I'm guessing that the problem is in the overhead unit itself. All of the other functions (compass, mileage, range) work just fine. I've seen several threads about the overhead dying completely as chips rattle loose. Is it also common for just specific functions to go out as things start to shake apart?

Mid- july I had the compressor rebuilt when the A/C suddenly started blowing warm air one week prior to a 1200 mile road trip.
Two weeks later the car wouldn't start. The battery (still under warranty) checked out as "good" was charged up and started the car fine. It needed an oil change before we headed home and the lube shop said that the coolant was low. I mentioned that I thought this was strange since I just had the compressor fixed and the guy and the quick lube just shrugged and I paid to top off the coolant. The next morning we set out towards home- 1200 more miles.
About 100 miles into the trip I noticed the A/C didn't seem to be blowing very cold. It was cool. Not cold. It was better after we stopped the car for lunch and that lasted for about 5 miles. When we stopped, our car was leaking copious amounts of fluids from both the engine and the passenger rear side of the car. By about 300 miles into the trip, the rear AC wasn't blowing at all. By 500 miles in NOTHING WAS BLOWING. Still leaking tons of fluids. Seemingly water.
We drove through the night with complaints of heat from the kids. Parked the car in the driveway. I moved the car into the garage... and I turned on the A/c to see if it was now working. The engine started to scream and smoke was rising from the hood. This didn't stop when I turned off the A/C.
The next morning, the battery was dead again. I had it towed to our mechanic. Other than the battery he could find nothing wrong. No noises. no smoke. A/C blowing AND it's blowing cold. Possible leak from the compressor (which I told him was under warranty from the guys who put it in and asked him not to touch it). They charged the battery.
I drove it to the A/C guys (A/C is blowing fine). They admit the A/C isn't as cool as one might hope. They drive it. Seems fine. Possible Coolant leak, but it's raining and they can't find the leak. They keep the car overnight. The Battery is dead the next morning. They replace the battery with a loaner. I'm desperate for my car. I pick it up and agree to bring it back in a few days to have them check the coolant levels and the battery.
NOW... Car starts, but it seems sluggish. The car revs like a formula 1 race car from 1st gear through 4th (maybe). The A/C is blowing cold (What the?? Blowing and cold?). Still leaking a lot of fluids (condensation?). Why? AND the check engine light has never gone on. What is wrong with my car???

My '06 Pontiac Vibe sometimes has one headlight out. When it's on as a daytime light, or on normally, the right headlight is not working. As a high-beam, it comes back on. It did this for a few days, then came back to normal after I hit a hard bump. Now it's back out again. It sure sounds like a loose wire to me, but I can't find it by jiggling wires behind the light assembly.

My fiance's 2008 Saturn Astra no longer has AC. The compressor does nothing when AC is enabled. You can hear the engine bog slightly when the button is pressed so /SOMETHING/ is happening, but the compressor never budges. My first instinct was to check the freon so I picked up a kit to recharge the system. Pressure was 60psi on the upper and lower ports. I saw some people commenting about blower relay's and resistors. The HAV system and blower work...fine minus AC.

Have a problem with the coolant gauge on their Passat? The temperature gauge on my 02 Passat sometimes reads normal (190) when I am driving and then all of a sudden it will drop back to 90. My first guess was the sending unit, but the dealer says it might be the gauge cluster too. I would think that if it was the gauge cluster the other gauges would act up too. ?

1994 f150 with 4.9L I6; 180k mi.
Parked vehicle last night after using it uneventfully for work the day before. Upon leaving the house at 11:30 AM, I noticed that I'd picked up a new mechanical noise. Nothing major; actually wasn't sure I heard anything at all.
As I drove to the store, I noticed it was idling slightly unsteady...much less so than a missing cylinder. I resolved to check the high-tension connectors when I got home for security. I glanced down at the gauges to check and see if my oil pressure was good; I then noticed coolant temp reading "high normal."
When I got out, I noticed a small pool of coolant forming. I looked at where the puddle was forming...the radiator hose had come off! (Actually separate from the radiator connector, as one might do if draining fluid without using the petcock.) I popped the hood: no unusual smells. Nothing seemed abnormally hot. Placing a finger against the head was uncomfortable, but not painful. Spit expectorated upon the head did not sizzle.
I then called my wife, explaining the situation, and walked back home 2 miles. We then took the spare car, bought antifreeze, and added it about an hour post-shutdown. Where the car was parked seemed wetter than the light drizzle allowed; daubing a finger in it and tasting gave a slight sweet taste.
I tend to check my fluid every so often (not every day, though) and coolant was verified as "full" as recently as 100 miles ago. (I don't make a habit of crawling underneath, though, so I couldn't tell you if hose had been slowly backing off or not.)
As to cause: is it plausible that this could happen without foul play? There have been a few vandalism incidents in the neighborhood; it's also possible that I [peeved] off a neighbor recently. I'm not about to go any further than fixing, though, unless there's really no other plausible explanation.
As to the mechanical questions: How much damage was done? Did I "catch it" in time? What is suggested as far as repairs/maintenance? (I was planning on doing a compression test, and keeping a close eye on fluid levels over the next 1,000 miles or so.) Engine sounds completely normal.

I just bought a 2010 LX and tonight I discovered that I may be able to play a digit copy DVD. So, the kids jumped in the car and inserted one of their movies(not Blu Ray) and we can only hear it. All we see in the video box is a blue screen.

I have a 97 Grand Prix GT with a 3800 engine. The "low coolant" light comes on occasionally, I checked the coolant in the radiator and reservoir, both are fine. I replaced the radiator cap. There are no signs of engine overheating. Could it be the thermostat? Also where is the sensor located?

I have a 2001 Pontiac Montana that was overheating. It was low on coolant, and using coolant. I took it to a mechanic who checked it out and found exhaust gases in the coolant. He initially told me that it was a bad head gasket. After doing a bit of research, I am told that it could also be an intake manifold gasket. I know I am losing coolant, but I cannot tell where. I don't think it is going into the oil, as my oil level does not go up. I do not see coolant leaking below the vehicle, so perhaps it is going into the exhaust? Or leaking slowly on top of the engine where it is burned off before it can go on the ground.
Is there any test I can do to determine which gasket is bad before tearing into the vehicle? I thought about sending an oil sample off to determine if I am getting any coolant in the oil, but I don't know if that would be useful information at this point.

Just purchased a 2008 2.0T Passat wagon, lux version. I believe my speedometer may be reading high by about 4 mph. I seem not to be keeping up with most of the traffic (assuming they are driving close to the posted speed limit). Not sure how to really check this out, but assuming the mile markers on the interstate are accurately spaced one mile apart, at 60 mph it should take me 60 seconds to cover the distance and at 70 mph it should take me 50 seconds to cover the distance. If my thinking is correct and upon doing that I find that it takes me about 66 seconds to cover the one mile at an indicated 70 mph on my speedometer
.
Is my thinking correct and/or is there another way to check? Have never been able to find a shop that has calibration equipment so I just resort to this method.

I am working on my daughters 1999 Grand Am with the 3.4 L V6. I was told by a shop that the heads gasket(s) were blown and needed to be replaced.
Well, the front head, cylinders 2,4,6 showed a "clean" cylinder2 while 4 & 6 looked ok. The rear head had no visible signs of leaking to a cylinder. After cleaning and reassembly, everything appears to be in order except for;
When starting from cold, the engine runs for about 15-30 sec. and the radiator fans come on. I thought that this was strange since this didn't happen before and I was told by someone that the fans don't come on until the coolant temp reaches 230 degrees.
After running the vehicle for about 20 minutes the heat to the interior is very good. In fact its downright HOT. However, the temp gauge on the dash reads "100". Thinking I broke the sensor while I was working on it, I replaced the sensor. No change.
The "Low Coolant" light on the dash is on, yet the level in the surge tank is above the full cold mark. I've replaced this sensor twice. No change.
