I have an 01 WJ that is having issues with the A/C blower turning off periodically. With the blower on high, it will shut off randomly. After about 10 minutes and after cycling it off and back on, the blower will come back on. Is there a limit switch that is kicking the blower off due to high current draw?

I'm not familiar with the WJ HVAC box, but I'm guessing a linear power module, not a resistor based setup.

If thats the case, its thermal management, most likely an over temp, not over current. Usually the power module will have a large aluminum finned heatsink mounted inside the HVAC module (the big plastic airbox) so the higher the fan speed, the more cooling.

You could try to remove it and see if its somehow dirty, otherwise its not going to be repairable.

Again, thats assuming its that style of blower control...

We need to know if you have the dual zone climate control or not.
