My A/C system works fine but it only works when the fan is on High Speed. Is this normal or is something wrong in the system. |

Sounds like you need a new fan motor resistor. It is located behind the glove box. Easy to replace, usually costs about $20 |

Both posts leave some ? on the table. To the OP are you saying your AC 1) cools only when the fan behind the grill is running on high or 2) cools fine but the fan in the cabin HVAC unit only runs in the high (#4 IIRC) position. Cannot help with #1 but if #2 then mrhemi is right. See my tech tips PDF at http://colorado4wheel.com/manuals/Jeep/KJ/ for how to and PN. Not as to PN you need to purchase based on noted PN or vehicle model to get the heavy duty one. |
