Hello! I have a problem that seems to be getting worse over time: My fan doesn't always come on when I push the climate control buttons. I thought it was only in the hotter weather, but now the same thing is happening, even though it's cooler. When the fan DOES work, it's strong on high and constant - no intermittency.
I can hear the vacuum working the valves when I press the buttons, so I think the controller is working. Any troubleshooting tips? Maybe a loose wire? How does one go about taking the controller out of the dash?
TIA
