GMC Sierra A/C Clutch | Chevy Malibu Blows Warm Air

2000 GMC Sierra 1500 4.3 Vortec v-6. The clutch went out on my A/C unit. Do I have to replace the whole system or can I replace the clutch and bearing only? Will I have any freon leak when I remove the clutch and bearing? For now I have rerouted the serpentine belt to continue to use the truck.

Depending on which type of air conditioning compressor is on your truck, yes you can just replace the clutch assembly. One style does require special tools and a special puller to remove the clutch assembly from the compressor, you can check with your local dealership to determine which style you have. I would always recommend doing a recovery of the system before any work is done on it. You may be better off replacing the entire compressor, because if there is an internal problem, or the shaft is damaged, you will need one anyway. Hate to do the same job twice! Good luck.

Chevy Malibu A/C Blows Warm Air

I have a problem with the a/c unit in my 1998 Chevy Malibu. I’m not getting any cool air when I turn it on. Why is this happening and how can i fix it?

Hwve you had the freon level checked?

Not that i no of. i just bought the car like 2 months ago and it just started doing this.

The first thing you need to do is have the freon level checked. This would need to be done at a shop. They will install gauges to check the pressures. If the system is low, the mechanic will have to add freon and check for leaks.

OK. Can i do that myself?

Only if you have a set of A/C gauges.

ok cool, but if that is not the problem then what?
If the problem is not due to low freon charge, then the electrical system would need to be looked at next. Specifically is the compressor engaging. If not, the control circuits would need to be tested. These did have a problem where you press the A/C button on the controller and the light would go off and on. This may be a bad control head.

OK thanks for the advice Mechanic JK. I’m going to recommend you to all my friends for help even though I don’t even no where you work. L.O.L!!!
