fan doesn't blow until 20 minutes of driving; used to come on immediately.
The heater used to come on fast; maybe 5 min. max & would be full force, but now it takes as long as 20 minutes before the fan comes on. The lights showing the fan full on are always working, but the fan isn't.
Does the temp gauge show the engine is warmed up? Or is it taking forever to warm up. If the engine isn't warming up as fast as it used to the thermostat is stuck open. HTH. -Jim
