Re: Climate Control Issues

On my (Black) 1992 LS, I've got some Climate control issues as well. Although I think I have a damaged mixer door, it's tricky to tell. If you've not already tried, see if "Def" makes a different. Try every setting in both AC/cooling and heating.

For me:
- heat won't come out of the main vents
- AC/cold will come out fine on any vents/settings
- heat will come out in Def (out of the window defroster vents

Living in California, just having heat coming out the Def vents if good enough for me, so I've left it as is. But checking those conditions may help you advance you diagnoses.

Good luck!
Ian.
