[scampi]

Hi!

I very hope to find it your forum!
I m hungarian and my english bad, sorry.

I have problem with my lincoln.

So this morning i change the original radio unit and everything work fine, but the car everytime on max heating no A/C!

The compressor ok and start it.
The A/C command unit work fine.
The temp sensor work fine.

My question is: on this car the air mixing drivered with one vacum valve or electric motor? Where i can find it?

Or any suggestion?

Thank you!

Hello

I believe there is three vac. pots under the dash that operate blend doors. There are located under the dash in the center area. There is a white flat blend door module that is buried in there quite deep also. You can see it if you flip the glove box all the way out and just let it hang, it's over to the left side. See link below for a picture of the blend door module.
