Hey Devils's Advocate (HVAC fix)

I just re-read your "interesting HVAC fix" thread in anticipation of receiving my new blower motor.

Your solution seems great...as I have very little floor heat.

How do I know which servo is which? I remember different colored vac hoses from doing the heater core but paid little attention to what they did.

Thanks, graba

Re: Hey Devils's Advocate (HVAC fix)

if you open the back of the ac programmer (cardboard) you will see the four vacuum switches. A row of three and one other. The one by itself is the recirc flap, the row of three from left to right (assuming the loner is in the upper right and the row is across the bottom) is floor servo, bi-level, vent. I don't recall exactly the colors of the lines (of course i generally don't pay as much attention to color anyway as I am color blind). By the way these cars generally don't have the greatest floor heat (atleast in comparison to most other cars I've had) so make sure that you actually have a problem to fix before proceeding, also be certain that the boot that goes from the heater box to feed the rear vents and underseat ducts gets properly fitted, it seems to be often overlooked by people when re-installing the heater box.

Re: Hey Devils's Advocate (HVAC fix)

Thanks, DA. I have NO heat to the back seat vents...but occasionally seem to have a little floor heat. The fan should be here today or tomorrow...hope my back is ready for it!
