Just wanted to pass this on due to the recent posts on A/C problems (ie: everyting seems to working but takes a long time to cool). For those who already know this I apologize, for those that don't, it may be the cause of some A/C (or lack thereof) problems.
---- The heater control valve, in my FSM is called the A/C water valve. If you don't know where it is, it is(on the 3FE)on the firewall top center behind the throttle and tranny kickdown cables. (Wish I could post a pic) :-\ Anyway check to see if yours is closing and seating fully (move the temperature slider from cold to hot and back). If it is not or you're not sure, then try this test :
From cold start without A/C running check the outlet hose going into the firewall with your hand, if it gets hot while the vehicle is warming up then the valve isn't seating and allowing hot water to get to the evaporator. Not harmful in itself, the freon will eventually over come and cool it down unless the flow of hot water is equal to or greater than the cold water coming in.
If the valve is bad, the good news is the part is only about 50-75 bucks. I don't have the PN (C-dan?) but it listed (where I was looking) as the heater control valve $ 53.20.
Hope that helps someone cause it is 106F today in the sunshine state!!!!! 8)
