No heat after oil change.
I recently purchased a new to me 91 6 cylinder YJ, and decided to change the oil in it, also changed the air filter. The old oil filter was on VERY tight and took a bit of wrenching and cussing to get off. Finished the oil change and while driving to work realized the heater no longer blows hot air, but the fan is still working on all settings just no hot air. My question is there something near the oil filter I could have hit that could be causing this. And this morning before the oil change while running around the heater was working.
Can't think of anything. Is your thermostat working? Was the jeep warmed up well ? Jeep heaters are pretty basic, you have a hot water line going in the firewall into the heater core (is this line hot to the touch?) it comes back out (maybe a little cooler). You have flaps inside the jeep heater housing, check that your flaps are opening and closing when you move your heater lever, you should hear them moving open and closed.
The heater one is back towards the firewall in front of the gear shift. It has a cable and plastic piece holding it to a L shaped lever. If the cable came off the flap won't direct the hot air.
