Cool; gald it was already there; makes life easier.

Keep and eye on the blower switch inside the haet/cool selector. In fact, if you are under the dash, inspect this switch for any signs of heat and distortion on the plastic body. The blower draws a LOT of amps running on high, and the switch contacts for the blower inside of this assembly can get corroded and then they will heat up, warp the body all to heck, and fail. There is a good sticky at the top of this sub-forum on that.
