When I turn my unit on I only get heat or air blowing in the back and not from the front vents.

It sounds like you have a front blower motor that is not working. If you turn the rear air off do you not hear any fan running up front? If so I would start by checking the fuses. Here is a guide and the fuse panel diagrams to help us figure out whats wrong. Here are the complete fuse panel and relay location diagrams for you (below).

Check fuses number 8 and 19.

Please let us know what you find. We are interested to see what it is.

Cheers, Ken

The fan was just stuck, so I sprayed a little wd40 and it’s back to working. Thanks for your time and patience with my problem. I also have another situation with my vehicle if you can help me with it. I’m hear a scrubbing noise coming from the rear driver side whenever I go into a curve and the pressure and weight of the vehicle is on that side. What causes that and is it expensive to fix. And this is the same vehicle.
