I recently changed the battery in my 96 Buick Park Ave and when re-connected, my climate control is now displayed in Celsius. How do I get it back to Fahrenheit? I could not find an answer in the owners manual.

Look for a button that has F/C. Dont know where it is on your model. But it is there.

mine has a button next to the cluster for everything (temps gallons speed.) before i knew about it and had to replace the battery i thought i was doing 60 or so at 35 lol. its called eng/met meaning english/ metric. i have no idea where it would be on your car considering its a different body, but id assume its the same concept. if im not mistaken we have the same climate control module.

I've looked everywhere for an ENG/MET button, from one end of the dash to the other including in the glove box. There is no such animal visible. I even took it to a Buick garage. They couldn't find it either!!!

If you don't have a button, then there is a wire coming off the climate control that gets grounded to change the reading.

In my experience with the 1997 SSEi, GM changed the dashboard wiring harness. In all models, Canadian and US they had a wire from a passenger floorboard ground to the main connector of the dash. On US models there was a wire from that main connector to the HUD. On the Canandian models the wire didn't continue after the main connector. The grounding of the US version caused you to see MPH and the Canadian woudl see KPH.

Likely your wire is loose, not grounded or something else occurred. Having an FSM that showed the schematic would tell us exactly what is up wtih it.

A/C not coming out of vents. Vent doors not opening, but instead comes out of defrost and floor. Any suggestions?

Yes, start up a fresh thread with a good title for that issue. That way when folks search in teh future they don't skip over it based on it looking like a display issue.

moved to it'* proper Mechanical Section. General Chat is for items that affect all platforms and "General Chat". It really helps the GearHeads, others with ownership of same/similar Models, the Forum regarding search bots, and our own internal search engine when we keep things in order. Thanx.
