That did not work, the key fob will not work either.

thanks, I left it over night and will connect it and see what happens.

The truck is a 2014 GMC Sierra

I disconnected the negative cable form the battery to hopefully reset the air conditioner controls for the dual temp control. ( driver side was warmer that passenger). I had the cable off for 15 seconds, when I reconnected it the horn ,hazard lights, high beams came on. When I turn the key the wipers and washer fluid comes on for about 15 second. The truck still starts . I spoke to my auto parts guy he said the BCM Module may be faulty. The truck ran fine and I had no issues besides the AC actuator . Any help would be appreciated
