As the title says, I have a 02 #746 The fan control on the drivers side is on the lowest setting and will not respond to higher fan control positions.

Thus far I found a clicking relay on the small relay rack behind the dash (per Newell service), I replaced the relay, no change.

I swapped the drivers side blower control wiring over to the passengers side to make sure the switch was ok, I ran the passengers side on all speeds of the drivers switch control, it worked so the switch is ok.

We swapped the two resistors that were next to all the relays no change in drivers side blower, assuming two resistors for the two blower controls, no change.

I am not sure what else to try at this point, other than rerouting the pass side into the drivers in the short term. I know that is not the fix. but it'll only be a few months before the fall is here and one definitely need to have a working defrost system to clear those windows up front. 

I am unable to check the resistor at the blower motor cause well I cant even see the thing. I am assuming there is a resistor at the motor, could be wrong on this.

I am not afraid to tear the dash down but I just have no idea how its all put together and I don't want to break something yanking on it. I've asked Creslie if there are any step by step directions, I kind of doubt it since each rig is different

Oh the joy of trying to fix things, nothing like having cold ac but not have the cool running over your face cause you cant move the air!! LOL, LOL  not funny but if I don't laugh I may cry!
