I would like specifics not just something like under the dash or on the fire wall. If someone knows where diagrams or pictures are that would be a great help. So far I have felt the heater hoses while the engine was hot and running, with the heater on and one was cold. I had flushed it with the tee that was already in the line. I hope it was the right line. It was the one that was hot. I have gone with out heat in the summer a air in the winter so I think it is the heater control valve. At best a clogged heater core. Any confirmation that I am on the right track would be appreciated. Also is this a difficult fix to get at?
Where is Heater Control Valve. on a 91 Buick Park Ave. ?
