Hi,

I have a 1993 Suburban that I just bought. The heater control doesn't seem to work. The fan turns on but will blow only air out of the dash vents. It won't blow any air out of the defroster vents or the floor vents. Anyone know whats wrong with it? Is it the control panel itself or something other under the dash?

Thanks in advance!

i made a writeup on this issue. if you got small hands and give yourself time it can be done the dealer wants $1200 to replace the motor. i got a replacement at pick n pull for $5. the 3 different door motors are the same so the dash blend door is in the front center and the the recycle door is alittle bit harder but can be done in 45 min and the rear ac/heat motor is the same. i got 4-5 units at the recycle yard......mike
