a week after the resistor pack blew. no big deal replaced, all OK. NOW jeep doesn't heat like it used to or as quick as it used to. Also notice a noise coming from the heat system when its in certain positions. Dealership said the system goes through a self test mode and that the system was operating normally. Well if it is in self test mode all the time isn't that wrong? the only time the noise stops is if the jeep is off. They said it is a vacuum system but the temp door is electrically operated. Heat still unacceptable. Haven t check level of coolant YET. t stat working, engine gauge rises and stops in middle. But will eliminate that as well. any other ideas? your help would be appreciated thanks in advance.
The gauge should rise to the middle-ish and then drop again when the thermostat pops, not stay in the middle.
Is it a matter of the heat not getting hot or not coming through the correct vents?
Just thinking the blend door could be stuck
