Recently replaced blower motor. It was causing the blower resister to go bad repeatedly.

Everything was working fine for about three to four days. Then while driving, the a/c stopped blowing cold air. I turned the a/c off for a few minutes and then when I turned it on again, white smoke started coming out from the right side of the hood. Thought the car overheated but that wasn't the case. Turned the car off for a few minutes. Restarted the engine, and there was no white smoke. Turned the a/c on, still no white smoke but no cold air either. I thought system had leaked and all the freon was lost. Pressed on the low pressure port for a second to do a quick check if system still had charge. Freon gushed out with pressure so system still has charge. Now when I turn the ac on, I hear noise as if there is no lubricant in a bearing.

Did my clutch burn. If so then can I replace the clutch without discharging the system. If its no the clutch then what else could it be. Could the blower motor change have caused it, and would it cause again after I do what repair is necessary.

Do you
have the same problem?

Yes the ac compressor has locked up and needs to be replaced here is guide that will help you get started also you will need to vacuum down and recharge the system. I would replace the receiver dryer and the expansion valve as well because debris from the compressor will clog the system.

You were right I got a new compressor and then followed the guides and got the job done It cost me $234.00 for the compressor and 43.00 for the expansion block. This site is great!
