Oldsmobile/Buick Repair: Olds / Bravada / Air Cond Issues, olds bravada, air cond

Question
My car - 2000 Bravada, V6.
When the car parked in hot weather, eg about 100 deg, the AC will not come on when the car is started. The AC light blinks 3 times and then goes out. After a few minutes driving, it seem to come on and all is OK. Also, the transmission does not seem to shift properly during this period also.
I am wondering if this is a "computer" problem of some kind - just started happening this summer.

Answer
Hi
Try this first.....
unhook BOTH battery terminals from the battery.
now touch them together, UNHOOKED from the battery, for about 30 seconds.
then, reattach the POSITIVE first, then the negative.
(Your clearing out Logic Lock)
Check it.
If it works, GREAT!
If not, follow post back.
Hope this helps.
Good Luck
