94 LeSabre Climate Control issue

[PoconoCharlie]

I am having problems with my 94 LeSabre climate control; incorrect exterior temp display (shows 10-30 degrees cooler than actually is), heat on drivers side, cold air on passenger (regardless of dual setting), and the external temp display blinks on start-up (is this an erorr code?).



Many thanks.

Anyone have a clue where the climate-control module is located?

Must be under the hood some place, near the firewall I imagine.

Anyone?

I'm having the exact same problem, did you ever find an answer to this??

The programmer that controls the movements of the vacuum valves is behind the glovebox, above the passenger's toes. The blinking indicates an error. You 94 may be able to display the exact code. Maybe someone has the procedure.

Later models wouldn't give up the codes without a scanning tool like the scan II.

If it's giving a strange exterior temperature you may have a bad connection at the sensor or a bad sensor. It is on the vertical support for the hood latch in front of the radiator about halfway down. It's relatively inexpensive from what I can tell. Check the connection on it.
