How do you change the heater control valve in a 1995 Pontiac Transport?
very hard to do, you must lean over the top of the engine to disconnect the hose at the heater core where the hose comes thru the firewall, then do the rest of the work from underneath the van on the passengers side. altho i found it is a bit easier if you remove the power steering pump and reach your hands down to the valve, aproximatly on top of the oil filter.
