After driving my car for about 10 minutes I start hearing this squeak like a loose belt, but I have also noticed that I can't turn on the heat or ac or else the car will die.

There is a pulley on the lower left side that seems to be the problem. I am not sure it is it spinning, and it seems to be wobbly.

What does this sound like to you guys? Do you think it could be this pulley, and how is it to replace?

 

The lower left side pulley is the A/C compressor. If it was loose and/or the compressor was going bad the increased drag on the pulley would put strain on the crank pulley, so it's very possible that's your problem. It could just be the pulley/clutch, but it also might be the entire compressor.

 

I'll check that out. I should be able to tighten it with a socket or wrench right? I will try that, and if anything I might have to pull the whole compressor? or can I replace the pulley?

 

Does the car die when u turn on any other electrical item? Headlights or other stuff? What does your volt meter read? How old is your battery? After u check the other stuff suggested u might want to check your electrical system. A belt squeel or alt whine? Just something else to check. Also check tensioner they can make noise as well.

 

They make delete pulleys that replace the ac compressor pretty cheap think I paid less than 40 for my from summit alot better than buying a new compressor or a used one for it to **** on u again

 

-Check voltage while off at battery
-Check voltage while on not running
-Check voltage while on and running

All three should be 12-14VDC

Then monitor your voltage while you turn on the heat/AC. Note any changes in voltage.

When you first turn the car on, see if that pulley is turning. Then have someone watch the pulley and listen to that area of the car while the car is running, and turn on the A/C. You should hear a click. If at this point, the car dies, the compressor might be stalling out your motor. Time to replace. If you do not hear a click, you probably will need a new A/C clutch.

At this point, I would really make sure your electrical system is free of issues. It sounds more like an electrical issue than an HVAC issue. Could be a bad ground somewhere, really could be anything, definitely going to need more info. Start with answering some of the questions that have been asked so far.

Good luck.

 

The battery is a few months old. I don't think it's the alt or a belt, and the battery has full charge and nothing else makes the car die.

 

If i floor it and turn on the ac it won't die, but soon as i let up on the pedal it will stall.

 

I will be honest. IMO it sounds like the pump is shot and when the clutch engages, it causes so much drag on the engine it literally stops it in its tracks. I'm not well versed on troubleshooting A/C but I would start there. Let me check my FSM when I get home and see if I can get you a primer on troubleshooting A/C.
