Question about 1991 Plymouth Acclaim
Car has 250k miles. Have backflushed the heater with std garden hose - flows freely. Heater bypass door seems to be closing.
There is a water control valve near the firewall where the heater hoses go in to the heater core. Make sure your hoses feel hot when engine is fully warmed up.. one should be hot and the other cooler as it is your return. the water control valve might be faulty not letting water enough get into the core. thanks jerry holler if you need more..
