My ac / heat blower fan does not work. Front or back. Help.

 

what vehicle? any codes? they don't work at all or in certain speeds?

 

2003 Tahoe. No codes. Do not work at any speed.

 

check all your fuses in the under hood fuse box,left driver side fuse panel and also the right side fuse panel inside the vehicle.if you haven,t checked your fuses check those first.if you lose power to one side of the hvac control panel it won,t power the front or rear heat/ac system.

 

Start with fuses, switch and wiring.

 

Thanks.

 

Fuses are good.
