When I got this X last year, the PO had added a manual valve under the '"hood" to replace the broken internal heater valve. Tired of getting in & out of the car to turn the heat on & off (especially now with the ambient temps all over the place.
Found a way to stick some more Volvo parts in my X ....
700 series heater control valve, Evap solenoid from 900 series, ran wiring to one of the blank switches on the console for solenoid power. I tried using a rheostat to modulate the solenoid, and bleed off vacuum, but the soleniod is only on/off, drop below 12v & it just shuts off.
