Question about 1993 GMC Sierra K1500
1999 Mecury Cougar. Heater valve evidently broken. Ex reached under the glove box and did something - moved a flap or something and it worked. Then undid it for a/c during the summer. Cold now and he's gone. What did he do?
He moved the diverter flap and unhooked the cable going to the heater control. If you look down there you should be able to see it and hook it back up.
