Question about 2004 Jeep Grand Cherokee
HVAC? the cab heater is dead or weak.?
1: does fan blow?
2; is heater lever to max.?
3: is mode lever at heat?
4: does engine reach and hold at 180F or more? no guess, this really is the first thing, (mechanics) that must work first.
no engine heat , gives you no cab heat. ever.
are you handy ,or just want wild guessing
if handy ,all ways it can fail are here.
the system is simple, its only a heat exhanger.
but is complex do to modes.
here is the list
a mech, knows its 3 reasons (pure physics)
1: engine not hot.
2: coolant not flowing in cab rad core.
3: air not flowing through cab core.
just 3 possible, in physics.
the tests are simple.
