The A/C stopped blowing abruptly. I still feel cool air flowing through vents.

Hello,

It sounds like the blower motor has gone bad or you have a fuse # 13, 15, 16, or 31 out. If the fuse is good lets check for power and ground at the blower. Here is a guide to help us get started the wiring diagrams so you can see how it works and the blower motor location below:

and

Check out the diagrams (below). Please run some tests and get back to us.

Cheers, Ken

Thanks so much for your reply. I believe it is the blower fan motor. There are times the system will start to blow cool air at like medium only speed only. Do not think it could come on randomly if bad fuse.

Yep, it sure sounds like it. Let me know after you replace it and if you can take pictures and upload them in your response that would be great. Also, check for power and ground at the motor to confirm the issue.
