At the beginning of the summer, the A/C on my Grand Cherokee stopped blowing cold. Local shop put some dye in the system and found that the core behind the firewall was leaking. The evaporator canister (right name?) under the hood was pretty rusted as well. The shop replaced both parts and the A/C worked great.<br /><br />Not that it isn't unbelievable hot here in Florida, I tried to use the heat, and it does not work. Took it back to the shop and the tech said the calibration on the air blender door was off. He did some research to fix it and decided removing the car battery for a while would fix it. <br /><br />One other note, the A/C and heat controls are the normal ones where you turn a dial for the temp, not the fancy digital ones.<br /><br />My wife mainly drives the Jeep, so I didn't check it myself after it was re-calibrated. Over the weekend, I did, and it does not blow hot air at all.<br /><br />Anyone have any suggestions on how to try and trouble shoot this thing myself. We can take it back to the ship, but my wife is on bed rest until the impatient baby she is carrying decides to be born (which is anytime between now and mid January)<br /><br />Scooch
