W126 Climate control gremlins??

[R@Z()R]

I recently replaced my performed an AC recharge of my car(replaced compressor,expansion valve and r/d and a good flushing put R12 back in) and all is good. Tonite my daughter complained she was cold and I turned the dial toward the heat and the 'recirc' button/light flashed and was clicking a couple times and then max heat came from the defrost. It would not adjust after that (back to clod etc.) just max defrost.

Last year in August I replaced the CC PB panel and the blower motor.
I also replaced the porcupine today as I got one off eBay on a good deal and thought I may need it.

Checked the monovalve and its ok(replaced 2 years ago.)

The recirc light/switch blinks/clicks a few times and if I dont 'feather it' back towards cool I lose cool altogether. I did this with the replaced blower reg and the old one. To me it sounds like maybe a relay problem or is it a problem with the temp potentiometer in the CC pb??


PS-- I don't have a layout of the relays only fuses. A relay diagram would be appreciated.

Thanks
