No front heat/air but rear works fine

No front heat/air but rear works fine

Postby Wizard16 [OP] » November 3rd 2010, 12:19pm

My front defrost/heat & air will not work but my rear air and heat work fine. I don't think it is my blower since it blowing in the back of the van. Any ideas on what would make this happen?

There should be two separate blower motors with two separate switches. If the front one isn't working, you could start by checking the fuses. I think checking with a test lite works best. If the fuses are good, check for power and ground at the blower motor under the hood, with the key on and blower on high. Here's a link to a picture if it helps.

Try this one. Look under heating, ventilation, and air conditioning. It shows both motors, but the caption is wrong for the one your looking for. It's on the passenger side out under the hood. The picture isn't too good but that's basically what it looks like. IIRC the hot wire is purple and there should be a black ground wire on a spade connector attached to one of the mounting bolts.

It's a picture under the hood on the passenger side, showing the wires to be tested.
