I have a 2000 jeep grand cherokee,
the heater motor isn't working, the motor works fine, the fuses are
fine, i was thinking it could be the heater controls, it has climate
control and the seperate switches for the passenger and driver, it
could also be the thing that stops the heater working untill the motor
reaches 50 degrees. does anyone have any other ideas or know how i can
check to find out exactly what the problem is.
thanks
Joe

I had an issue with my heater blowing cold air all the time. As it
turned out, I was low on radiator fluid. I fixed the leak, filled it
up, and it's been working fine ever since.

It could be the blower motor speed selector switch in the dash. I've
replaced mine several times on my 94. It might also be the resistor
pack for the blower motor has gone bad (in the 94 cherokee, these are
found in the interior passenger side wheel well on the lower left
below the dash behind a small plastic panel). One other thought is
perhaps also a bad ignition switch? Will it come on if you jiggle
the key? I've had to replace my ignition switch about 5 times. Hope
this helps.
