I have a 2003 Cadillac STS. A/C works fine however, heat blows cold. Using a simple temperature test I have verified coolant appears to be flowing through heater core, not 100% certain but trouble isn’t leading me that way. I have checked all the actuators I can find, one on left and right side of console. One is bad however it is located lower rear left/drivers side and appears to function for rear controls on which nothing works.
I even pulled the cabin filter and while it was nasty and corroded, I believe sufficient air should have passed though. Anyways I am testing without it being reinstalled. I just reattached the cover so air would not leak out the cabin filter access port.
I am at a loss and could use some guidance. I am now thing of taking apart the entire duct work assembly under the dash. I rather not since access it and the various screws holding its various parts will suck.
Anyone who believes the know what’s wrong chime in, I will pay for a solution.
