i am taking my 98 gs to the local dealer for diagnosis . i believe that the climate control head is fried again . had one replaced under warranty in 2001 . this is a known problem & a tsb was issued for it . however , since it is not a safety issue , there is no recall . the climate control is very sensitive to voltage fluctuations or surges or the disconnect-reconnecting of the battery cables , which i have not done since the unit was replaced the first time . one day the a/c worked great , the next day only heat . all the fuses & replays are fine . when the unit failed the first time , it was in the middle of january and the a/c worked , but no heat ! i think the head is over $650 cdn + labour + diagnosis . my 90 bonne sse had climate control like the buick but it never failed in 8 years of ownership ! pi??es me off !! such poor quality engineering !
I'd side-step the dealership service and march it right up the corporate service ladder - your car has a know history for this part being defective and you shouldn't have to pay for their screw-ups
Is the display fading or is the entire unit shot? This is a problem common to the 97.5 - 99 Gs's. I believe they can be easily fixed with a simple soldering iron. More info can be found here: http://www.regalgs.org/climate.htm
the display is bright & solid . i also belong to the regal.org site & a number of guys on that site have had this problem .
update turned out the problem was the electronic clutch on the a/c pump . at the same time they replaced a seal on that pump and did a recharge . total cost $731 cdn !!! a/c works now .
