Problem : I have a 95 Suburban, that?s got a life of it?s own ! , when it?s cold the heat barely trickles from the vents, the defroster also act?s the same? , however , occasionally the heat decides to work ! when it feels like it. I haven?t torn apart the dash yet but I almost ready to if the temperature gets above 20 degrees.
Also some of the display light cluster by the heater work intermittently when the heater does as well. Please help before I call Mr. Expensive Wrench ?
