    Floor heat....

    Just did some troubleshooting in my service manual. Says that when you don't get heat from the floor selector in either auto or manual mode, it is likely the thermal blower lockout switch. Is this a common thing to replace in these cars? Never seen one in a GM, sorry.

    Thanks-

        I jumped the connection and it came right on, but then, I hooked up the connector and tapped on the 'valve' and the blower came right on. Must be loose connection in there. Thanks for all the help guys. I may get another TBL switch later on. But i also like the jump with fuse idea.
