Question about Cars & Trucks
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.

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

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.

When I turn on the heat in my 2004 mazda mpv the front air vents blow heat but the rear air vents are blowing cold. I have adjusted every setting is there something I am overlooking.
