'90 Coupe Quattro runs erratic with HVAC on?

Run fine with HVAC off, but when on the motor seems to vary on how much power it has.
Also, temp gauge indicates slow to warm up and never gets to the 1/4 mark.
Thanks for any help.

Revise

Actually the car runs and warms up fine w/ hvac off or on Econ mode. Only when hvac is in auto that there is erratic/cool running. It seems like the A/C runs max all the time in auto mode?
Thanks,
Steve
