Ladies and Gentlemen:
I have climate control and the fan works on low. The A/C and heat work, but the fan will not go to medium or high, even if put on high. A few weeks ago i needed to repair the wiring harness that burnt up by the relays under the hood. It worked after the repair. i have the manual and have started examining the wirning and connections and will start troublshooting soon. Any additional suggestions from the experiance of the Team Buick members would be great.
Thanks,
John
