So I've been having problems with my fan speeds all of a sudden dying down and almost stopping when I have been driving for a while, such as going to work, all of a sudden about halfway to work the air coming from the vents cut out and barely come out. So I started to think it was the blower motor resistor, so I got a new blower motor resistor and a new blower motor and installed them the other day. I turned the car on after installing and the air blew great out of the vents, better than before. So then the next day I drove to work, then about halfway there I noticed that the same problem was happening, the air coming from the vents started to cut out again. In order to get air through the vents again I have to turn the HVAC to off, wait a few minutes, then I turn it back on and it starts blowing air again. I don't know what else to do now. Could it be possible that the HVAC Control Assembly (where the knobs are) is failing and I need a new one? I'm not sure what else to check or replace, any help will be greatly appreciated, thanks in advance.
