I have a 97 GMC Suburban, the rear vents blow air/heat. Nothing coming out of the front dash vents. Fuse under the hood looks good, what could it be?:confused:

its probally your blower motor, its located inside on the passenger side, right above where the passenger feet are. Put the blower on high and tap on it with a screw driver handle. It might start running. brushes might be worn out.

Check to see if the blower motor is getting 12 volts positive when it's switched on. If so, replace blower motor. If not, troubleshoot the system.
