My son's having a problem with his Magnum heater that I thought I"d ask about here.
It's a 2005 Magnum 2.7 and the engine comes up to temp fine, heater fan works but it doesn't blow warm/hot air into the passenger compartment unless he takes it on the freeway. It's been very cold here but the fact that it only blows warm air when he takes it on the freeway is a little confusing since the engine temp gauge shows it's up to temp.
Anyone familiar with this issue on this model or engine?
have the same problem?
