Curious if anyone has experienced/resolved this issue before. My blower fan will turn on/off by itself while driving. All of the buttons/displays respond properly for climate control (temp will cool/heat), however the blower fan will not work at times. To be clear, when the fan is working it will respond to controls. This is an intermittent problem, sometimes the system works properly, and sometimes the fan will not blow at all.
