A/C Recirculation Servo

[urbanNINJA]

Just bought a '96 LX450. Literally just got it today!

I do have a bizarre issue that I can't seem to figure out. When the A/C is set to recirculate there is a servo/motor that drives an arm in the dash beside the glove box that continually spins. The arm was disconnected so I reconnected it to what I assume is the recirc flap under the dash. It just continually spins and causes the recirc to surge on and off. If I turn off recirc it stops and doesn't surge, but then I'm getting 100degree TX heat through the system... No bueno! What is the deal. Anyone experienced this. Is there a resistor or something that's bad. The recirc switch on the A/C controls is working, the servo is just not doing what it's supposed to. HELP!

This is my first post by the way. Looking forward to being a part of the forum!

No help, but same sentiments.

Looks like mine when she was a baby.

Thanks for the welcome guys!

I actually fixed my a/c issue. Dug into the dash behind the glove box and found the out of control servo/motor that wouldn't turn off. Not sure if the motor is supposed to disengage itself internally or if its controlled by the a/c amplifier or another relay or something. Anyway, I just unplugged the thing and got the flap to permanently sit in the recirc position. Who needs fresh air from outside anyway! It's 100+ in Texas this summer and I don't know that I've ever actually had a need for fresh air on any car I've ever owned. So it's working the way i want it to now. Still not a proper fix, but good enough for me for now! If anyone knows the proper fix let me know.

Also, fixed a floppy side mirror with the "zip tie fix" and got an ecu cel code sorted out. Not a bad first day!

Now I need to get the electric seats to work and moving back and forth!

Common problem on the seats, search and you will find many threads but here is one that helped me out:

My recirc servo went out so I disconnected it and it is now permanently on recirc. For where I live, it works since I've never (in any vehicle) used anything but recirc.
