The climate control system on my 99 STS is working intermittingly. When it is not working- the fan doesn't come on. Sometimes after quite a while the fan will kick in and things start working again. I noticed this with both heat and AC.:(
Any ideas on what's causing this problem??
Thanks,
Bill

Sounds like a failing (intermittent) fan, but before you replace it, check the plug for clean unbent contacts.

Your gonna want to have the soleniods checked out. I had a similar problem with mine. The heat worked fine, but ac only worked on the passenger side. Might seem like a different problem, but never-the-less...who knows with these cars. Either way, it will cost you $$ :banghead: . Maybe a cheap way out would to get a hold of a temp control panel from ebay, if that doesn't fix it, you can always sell it.
