My daughter has a 97 TJ, 4.0 auto. She hasn't had much heat out of the heater all winter. Last weekend I replaced cap, rotor, plugs and put in an OEM thermostat and sadly that seems to have made no difference. It was a 196 degree thermostat, had the jiggle valve, and no real difference.
What's my next step, heater core flush?
We're in CO and a good heater is nice to have.
