The Cold is Coming.. 97 TJ Heater Problem..
 

Hello again everyone,

I have posted about this before and tried a few things but had no
luck.
My 97 Tj Heat/AC will work on the first 3 settings Low/Med/MedHigh but
not high.
The AC cools good and it heats up ok. But when you turn the knob to
the highest setting it cuts off! Nothing comes off just silence..
Even when it is just the fan running.
Any ideas .. I checked the resister in the front by the battery and
also the one behind the glove box. They both checked out ok.
TIA for any suggestions. I really appreciate it!

Shawn

On the older Jeeps, high is it's own circuit with the lower speeds
routed through the resistor pack. I am thinking there should be a
heater relay in the power distribution center for high.

Re: The Cold is Coming.. 97 TJ Heater Problem..
 

Thanks for the response Mike! I saw a relay in the dis box by the
battery that says/ ac I changed it with no luck.
I also tried the on in the dash. If I take it out it doesn't work at
all and when replaced it doesn't help.

Thanks!
Shawn

If the resistor and blower motor relay are good then it is probably your
blower motor switch.
