i have a 93 Accord and my heating controls is stuck on the recirculation mode which means that when I drive my car, the windows fog up on me automatically. My question is this, where is the door to turn the recirculation mode on and off? I'm thinking if I can open it back up that I would be ok.

 

Do you turn the A/C on? The windows don't defog without the A/C.

 

AN old 4th gen, the ac might not be working - never came with it - and if not working the cost of repairs might be more than the op want to do.

OP - from the pass floor, look behind the glove box and see if you can locate the motor. Never had a 4th gen so not sure if the glove box has to come out to get to it? Here is a pic that I hope will help.

 

Issue may be due to one of the following:

• Faulty heater control panel
• Faulty Recirculation motor
• Stuck door or linkage

1. You can see if the recirculation motor can switch to fresh air by applying 12 volt power (+) and ground (-). Unplug the 3-pin gray harness connector (Connector C439) to the motor. Apply battery power (+) to the Yel/Blk wire and body ground (-) to the Grn/Wht wire to see if the motor will now switch to Fresh air mode.
2. Otherwise, you can try to manually move the linkage.

 

Thanks guys. I'll check on it when I get off from work this weekend.
