I have a problem with the climate control system. It seems that functions keep disappearing. To begin, The blower speed went from all speeds to low only. Some 5k miles later the heater/defrost doesn't work. Earlier last summer the a/c was charged but because of the low blower speed there was no cooling. From your collective experiances does this sound like a relay, computer or just a bad blower. I need to add that the vacuum system to deflect air to the individual ports stopped functioning. Please note that this has been a progressive problem rather than a "just quit working" scene. Any help is gratly appreciated. Thx Chip
