Yr 2000 ac not cooling on drivers side blows warm to cool air on drivers side and cold air on pass. side freeon checks good antifreeze checks good


1. Low freon. A mechanic once told me that the car will act like this when it needs a freon recharge. Such did not solve my problem, however. 2. Stuck door. There is supposedly a "door" (for want of a better term) inside the heating/cooling system that regulates temperature and/or cabin airflow. The door opens and closes according to the temperature and and dual climate settings selected. If this door gets stuck, it causes hot to blow out drivers side and cool on the passenger side. I am suspicious of this theory. Why would hot air correctly blow out of both sides? I had another mechanic tell me this one. 3. temperature sensor improperly reset. I read online that if the battery gets disconnected and reconnected improperly, it will cause a malfunction in the sensor responible for delivering the proper temp through the a/c system. The solutions posted were disconnect the battery and reconnect with negative terminal first; check all fuses that reference climate control, a/c , heater, etc in manual, remove for 15 seconds, reinsert or replace if necessary. This did nothing for me. However, I personally associate this intermittent problem with a battery reset. My wife's car has electrical problems (don't get me started) which necessitate frequent battery replacement. Everytime the battery has been disconnected, the problem starts again. 4. Computer malfunction. I also read that the problem may stem from the climate control interface itself (i.e. the thing with all of the temperature knobs and buttons). Replacing this is supposed to fix the problem. I have not tried this, and frankly, I refuse to do so. The only current solution I have ever found is patience. The problem seems to simply disappear after a while (albeit a long while). My wife and I both have Intrigues (Gasp!). They both have the same problem(s). Nothing works for either. Good luck. If you have success post your results.

Heat comes thru driver's side vents, but blows cold air thru passenger side vents


You likely have a faulty blend door. It could be electrically, mechanically related, or even a broken door. It may be the blend door motor, or possibly the temp sensor.

How can I fix


This is either an out of phase issue or a temperature control blend door or blend door motor actuator problem, it can also be the climate control module in the dash, 1st try disconnecting the battery for 5 min's to re-sync the climate control module, if this fails u will need to find out what blend door is the problem or if they are ok replace the automatic climate control module in the dash

there are two separate actuators for the rear system. one controls temperature and the other controls vents from head to feet. mine problem was the later. that acutuator for esv 2003 is 89018365. it is located just below third seat cup holder passenger side and can be replaced simply by removing cup holder. triangular shaped part with wire harness.

Only cold air on passenger side


I would assume with multiple people having the same problems, there should be a service bulletin on this issue. may want to call dealer with vin # to verify. sounds like a heater control issue under the dash. something i would leave to the experts for repair
