Funny that we just talked about this. Now my heater fan shuts down intermittently. I did notice this on my stereo in the past but it was due to a bad alternator putting out low voltage. The funny thing is my stereo is working fine so I think it’s something else. The whole heater display shuts right off sometimes and then comes back on and sometimes the lights stay on and the fan stops for a few seconds. Gonna have to post about it and see if anybody else has encountered that.
