the time and when it does start to move up in temp it won't go above 50 degrees but the AC will start working and works good. Than in a short time the temp starts going back down and than the AC begins to not working again. I have replaced the outdoor temp probe and the inside control box but the problem still continues.
I don't know were to look anymore and would really appreciate some help.

While driving my car this light comes on sometimes,and my car turns off in the middle of the street and all of the lights on the panel go crazy. Already changed the module and fuse box. No codes come up when we took it to the mechanic at the dealer. Only advice given from the mechanic is to wait until things get worse so codes will come up. I dont like that idea and it's dangerous driving a car that turns off at any given moment. Never had any other issues with this car. No one can figure out what is wrong. Sometimes it won't turn on

The one time I have had the code checked it seemed to be a heating thermostat. The engine is running cooler since I had the coolant reservoir elbows replaced with aluminum units rather than plastic.

happens all the time. with key in on position I turn signal on and all dash lights go out,they come back on when I shut signal off

My engine literally felt like it was stalling and I heard a slight knock. I pulled over to check my oil because the "change oil" and "service engine soon" lights came on. It was a quart low so I added a quart. I turned the car back on and the "change engine oil" light went off. Service engine soon didn't. I was able to drive no more than 15 mph the 2 miles home. If I drove any faster the car kept trying to cut out and the knocking was loud. Help?

while I am replacing both upper an lower intake gaskets/should the EGR valve be replace or can it be cleaned an re-installed?

should I replace the lower intake at same time,an also the ERG valve.Egr valve is expensive,can it be cleaned an reused or should it be replaced?

Not putting out cool air.

battery fine put on new starter had a major tune up

The vibration starts at around 35 mph when I press the accelerator and stops vibrating when you take your foot off the accelerator, occasionally I can also hear a knock when I stop, start rolling and make right turns. The knock and vibration is coming from the right front. I had the inner and outer tie rods replaced but the problem still persist, one of the techs says it might be my transmission but I say no when you can clearly hear and feel the vibration coming from the front.
Please help if you can

the girlfriend left the window down and it rained. now her passenger window wont roll up and her drivers window keep rolling down by its self.

Car runs great, seems to shift fine. Only problem is this accelerating problem from a stop. Service engine soon light came on, and I was told the shift solenoid code came up. Had computer cleared. Since then my door locks no longer automatically unlock when placed in park. Still having the accelerating problem. Engine sounds like it's laboring until you get going.

One of the three coils are bad! How do I determine one it is.?

One of my wipers works and the other doesnt why is that?
