Hello, I have a 1989 GL 10 AWD that has a defrost problem. This car has AC, which works, I can get heat but I can not switch between "Heat", "Bi-Level", and "Defrost". The Heat, Bi-Level, and Defrost buttons work but when any of these three are pressed it just stays on "Heat". I can switch from the 3 heat choices and the AC and it will switch back and forth, I just can’t switch between the 3 heat choices. Any help??

Thank you!

Thanks for helping identify the name. By doing a web search first using the name "oil separator cover gasket" and other searches with a name close to that I could not find any results. I also tried searching part vendors web pages using their category search and typing in the gasket name and could not find anything. Does anyone know where I can find on online? I will check my local parts supply shop and then if they can't help I will most likely go to the dealer or just make it out of cork board. Thanks again for all the help!!

What is the name of the gasket the is located on the engine block, behind the flyweel? It is kinda like an oil pan gasket (it in fact does seals oil). There is a mettle plate that fits over the top of the gasket anbd is held with like 6 bolts that are just like the oil pan bolt. This gasket was included in a Oil gasket set that included the pan gasket, mickey mouse gasket for the oil pump and a few more. Any names for it?????????
