The AC works. It blows cold on your feet, the front wind shield, the back seat vents. Just not on the front seat vents. I think it is something to do with a silenoid not switching. But I don't have any Idea where it would be.

The dealership can never get it to code. I turn the key to off and then it start right back up. It has done this sence the day I bought it.

is not very cold when running

I pulled that fuse and it corrected the problem awhile ago but I have forgotten the fuse position to pull and replace for 30 or forty seconds. Is the TCCM fuse at the powertrain control module 1 location?

Its leaking and we dont tow or off road with it

after scanning codes it gives me a throotle pedal position sensor switch

What could the problem be when this happens?

My air conditioner blows warm air when you first turn it on. If you move the thermostat up and down (from cold to hot) rapidly several times it will start blowing cold air like it is supposed to. At first it would do this every once in a while now it is doing it all the time. Once it come on it stays on, but if you stop engine for a while to run in to a store or something you need to do it again to get it to blow cool.

The noise is like a loud vibrating sound?


ran car to store ran good. Left store and it died will crank but fuel pump will not run.(already tried new pump same prob.) can anyone help

When I stop and my ac or heater is on my engine will idel down or cut off completely. No codes are coming up and I have had the throttle body cleaned since replacing my battery and alternator. What else can I do?

The radio works great only sometimes. When it doesnt only the driver side front speaker works. Does anybody know what may be causing that?

replaced actuator motor and did relearn procedure and they still will not opperate, getting power at connector they motors seem to move out of range when turned on.

I have had this issue checked 3 times so far and again the check engine light came back on after having the issue "fixed" by the dealership. They said it was a faulty part at first. What the heck is going on here. I just purchased the truck 3 weeks ago?

wiggle floor shifter and push button on shift handle and then lock will turn little more and key will release.I am thinking the park lock actuator located in the center console is bad.

Can the passenger side through off seven codes?

I tried bleeding my breaks in the rear but i am not getting and fluid back there. i did run the resivor dry could that be the problem?

6 cyl, two wheel drive, positive traction. I have owned it from the beginning. This Blazer has been garage kept.

Here is the problem. In this past year, there are many times that the breaking behavior on this Blazer is unexplainable.

Most of the time the braking works perfectly. Depresses down about half way to the floor, breaking is gentle, smooth and feels right. Other times it begins to pulsate as if I have a compromised rotor. The brake pedal is hard and doesn’t travel down as normal. Sometimes the pulsating just starts while I just driving. A bumping or pulsations which I can feel in the steering wheel, brake pedal and just overall in the vehicle. There have been times when I have to “punch” the break pedal, even when I am driving at speeds of 55 miles an hour to get the pulsating to stop. It is as if something in the brakes system is not releasing and/or just starts the breaking pulsating unexplainable. The only correction has been to stop the car and restart and the pulsating problem goes away and it seems right again.

I have had the brake calipers checked. They are well lubed and move freely, boots are in good condition. The behavior seemed like the ABS is trying to work for no reason at all. I was thinking that this was the problem. So, I pop out the fuse for the ABS.... This left my ABS & traction control, panel lights on and indicating the ABS is disabled.

The problem still occurs from time to time. So now I’m thinking there is something wrong with the computer which governs the whole braking system.

I would like to have some insight in to the possible problem. I have been to many auto service and dealerships service centers over my 45 years of driving.
Just to get jerked around by folks who can’t figure out a problem, and just starts to replace very expensive parts trying to eliminate the issue at a high cost to me.
I can’t afford this route. Just need to know what other possible reasons could cause my issue.

Only the passenger seat is affected and the up/down and seat back functions still work.

2008 trailblazer

Why would the tie rods be in such terrible condition?

Is there a history of this problem and is there a recall?

When I drive over a speed bump I hear squick come from the left wheel

85,00 miles

its only happened one other time, and it was also cold out then as well, aftre further investigation i found that the bolts on my plastic valve cover were loose. could this happen all the time? and how do i keep it from happening again?

For about 6 months now when I first start the car and go to take off the stability light with wrench comes on along with the traction assist light, if I turn the car off and restart it the light will go off, the last few days it will just come on while I am driving. I have read some post that talks about the steering wheel sensor may need replaced, is this a possibility, how do you know for sure and how do you change the sensor, I have found the sensor at autozone for about 120.00
