06 Chevy Suburban Dash fan stopped working

Yes dash control is bad most likely

There is a resistor that goes out on the odyssey and pilots for the blower motor. Does it blow on full speed? Is it both front and back that don't work?

Possible blend air door malfunction.

Had exact same problem with my 2006 Chevy Silverado 1500. Would blow hot air thru drivers vents only and sometimes if I turned truck off and restarted would blow air conditioner for a bit. Rec'd recall letter from Chevrolet in January for this problem.

you have a bad vacuum line some were, it may have come off the motor or cracked...

2 possible problems, #1 is the control switch on the dash has malfuntioned(less likely) , #2 is the motor under the dash that changes the blower position is not working properly.

Please rate my answer ............Thanks

replace blower motor resister

they run off of the same compressor if rear is cold and front is hot the hot and cold function in the heater box is not working possible cable problem ? or a vacum line under dash

if its the computer climate controlled series then it might be the the vents. what happenes some times is the vent wont switch over from hot to cold or vise-versa. i had the same problem but reversed, no heat in front and it worked up to the last time i had switched it from hot to cold.
give it a shot, best of luck

The hot/cold switch is probably bad.you have a blend door box that opens to let the cold air in and closes to let the hot air in.From what you are saying this part is no responding to the switch movement.Make sure power is at the switch and power should go through the switch when put on cold air this moves the blend door.Some times the blend door goes bad and has to be replaced its under the dash on the right side.
