OK FOLKS here is my next issue. The a/c has now started making a high pitch whine on high and it sounds like it is stuck on recirculate. next thing when i start from a stop light I here a slightly loud sssssssssssssshhhhhhhhhhhhhhhhhh noise from what i think is the tranny. Also when towing about 7.5k it seemed like it didn't want to shift. yes i was in tow haul and the speed was about 63 mph before it finally gave way to the next gear. is this part normal while towing b/c it doesn't do it each time and it was on a straight away when it did it.

 

a/c might be the broken blend door. mine broke and took like 3-4 hrs to fix
