95' Bonneville Climate Control Problems?
Help! I have a 95' Bonneville with intermittent climate control problems (at least that'* what I think!) Sometimes when I start car and drive....I can turn either the AC on or heat.....and nothing happens. The fan will show top speed but nothing happens....then after driving for awhile the unit just starts blowing?...I had the blend doors replaced few years ago and when it does decide to blow I can get cold AC or heat. Any ideas? I tried to get codes to read out by pushing off and warm buttons (same time) with key on (per previous post) but could not get codes to come up.... Any advice?
