Question about 2000 Jeep Grand Cherokee
does the fan run at full speed on high, sure it does, i bet.
the heater only works on a hot engine.
180F min. and holding. some go to 200F (on newer cars)
so does it? get fully hot, and NORMAL.
the heater uses ,engine coolant to steal its wasted heat.
1: bad or missing engine coolant thermostat.
2: RAD fans stuck on, or is just too cold.\
3: no location stated. and we do get posts from the yes, north pool. or up in high Canadian provinces??? or Norway?
up in alaska we keep some engines running full time (no heated garage)
and all have rad blocked 1/2 way with cardboard.
and some we spray the whole engine with foam to keep it warm.
so not stating location (not one ever in 4000 posts) we cant answer you.
what do we do, well, I point the IR PYRO gun that the thermostat
housing, (need photo?) and see 10 less that stat rating.
if 180 i see 170 if 200 i see 190.
this is the www, and we get posts from all over planet earth.
