Check the temp control switch by holding down the radio "ON" button and the radio "SCAN UP" button at the same time, which turns on the diagnostics for the temp control switch. If it checks out fine, then you may have a clogged heater core. I suggest having your cooling system flushed or flush it yourself to save money. You can get a flush and fill kit for around $5 at your local parts store, and you need a water hose. Buy new antifreeze, and follow the instructions on the flush and fill kit to flush your cooling system. Refill with antifreeze, and the heat should return to normal.

Make sure your control settings are correct, you may have a blend door issue, stick your head under dash on both sides and move the hot to cold control and see if anything isnmoving

SOURCE: Front air condition does not blow cold. Rear air condition does

sounds like a damper door in the front not working properly, these are actuated by the front temp control, the door is operated by either a manual cable, and electric actuator, or vacuum. I hope this helps you zero in on your problem. Merry Christmas

SOURCE: Rear a/c not blowing cold, front works fine.

you may not have enough refrigerant. a low charge can cause the rear in this dual system to not work for beans. charge with a can of uv and find the leak. fix the leak. evac the system and recharge. i think you take 4 lbs, but check the accumulator sticker. you may want to just change the accum at the same time.

Rear heater working ok , but front heater blows cold ?


Best case is you accidentally left the AC switch on... Check for pinched/bent hoses near firewall of passenger side. Worst case is the heater core is clogged. In this case someone can backflush the heater core to clear it. Good luck!
