I have been having intermittent problems with my A/C...meaning every couple of months. The A/C light will start blinking, and it will stop working. I have been able to turn it off and turn it back on again to get it to start working before. I have also changed the cabin air filter and it started working again...coincidence I don't know. It started messing up after someone at an oil changing place inspected the cabin air filter. Could this have anything to do with the problem? I am planning on taking it to a dealership soon, but I would like to know what to expect.

 

I took it to the dealership, and it was a relay that went bad. The air filter changes must have just been coincidence.
