Saturn Vue 06 AWD Electrical Problem
I have a similar problem to some posts where Vues won''t start when cold but opposite now very hot (possibly related) problem. This is by far my oddest auto problem to date. 06 Saturn Vue AWD... Bought car last fall. It has been a one owner and really taken car of. We have had no trouble with it until the ac stopped working.
Sorry so long. AC was failing and I had it checked out. Sometimes at highway speeds and mild temp (80s) it seemed to cool a little sometimes.. Two shops said the compressor was leaking so I ordered one and had it put in today. It was great to have the ac back especially since it has really heated up in OK (upper 90s today).
I picked up the car from the shop around noon yesterdayand the ac was ice cold. I set out to run some errands and drove about 45 min to first stop; working great. Then I drove about 35 min to 2nd stop; still great, 3 stop 15 min, still great. I stopped for a bite to eat and while in the drive through line (probably a 20 min wait) and temp of 98 outside the ac quit working! Annoying but I thought I would just go by the shop again as my errands were finished. I puled into a parking spot to put the mustard on my sandwich. As I was pulling out I heard a whining sound that I had not heard before. I wondered if my power steering was going out.. A few seconds later, my dash lit up and all lights came on, check engine, ABS,. I think all of them.. I thought I would turn it off and see if anything was noticeably wrong and I then tried to restart it. Everything was dead, with no power at all. No emergency flashers, I couldn't even open my door with the power unlock button. So, I got out of my car to explain to the man behind me that was by now honking.. I was at a Chic-fil-a and the nice kids working outside ran over and offered to push me backwards and into the restaurant parking lot next door. Still NOTHING electrical would work. Putting the key in the ignition didn't even cause a buzzing noise. I assumed the alternator had died and thus my battery had followed it also to its death.. I thought possibly this is related to the AC compressor (seizing) or a belt or ...??? So I called the garage that installed the ac compressor two hours previous. They had no idea, but offered to call a tow truck. Towing me for an hour back to their shop would have probably cost a fortune. While I was on the phone with them a couple of things started working and soon the radio came on and then everything worked. First time I tried to start the car the solenoid just clicked.. Then 2nd time a minute later the car started right up as normal. No warning lights were on. I still had a bit of a whine and I still wondered if the power steering was going out. I drove left and right in the parking lot to listen if the pitch would change or it would get louder. Nothing changed and it was a quiet whine. The shop asked if the ac worked. I didn't the nerve to try it. I drove back to them, staying off the major highways. I finally got the nerve to push the little snowflake button for the ac! Nothing. The ac would not come on, so I was convinced this had something to do with the ac. I made it back to their shop. Turned the car off, then on and it started and ran great like it always had. The mechanic came out to check it and said that the voltage or current was running uneven. I think that is what he said. One side of something was not the same as the other side. I don't think it was showing any codes then. The mechanic said that when he checked even the ac was working. Not that I didn't believe him, but I had to see this myself. I went out, started the car and yes, the ac snowflake light came on and it was blowing very cold again.
Ideas??? Alternator, serpentine belt or pulleys, or corroded connections (I've read connections under the wires under the fuse box can oxidize) or something else??
I left it at the shop and they are closed till Monday. The mechanic suggested ignition or computer.. I have read that that is rarely if ever the problem. I will talk with them Monday morning.
