    I have a 2014 Prostar and the heated mirrors aren’t working. When I activate the switch the indicator blinks rapidly instead of staying on like it used to. Was working fine when I parked her, came back the next morning and it was doing this. I’ve already checked all the fuses and circuit breakers on the passenger side dashboard and that all looks good. Any ideas on what might be the problem or what to check next?

    Could be the module that controls it. Ive had it happen on my freightshaker.

    Thanks, I’ll have my mechanic replace it and see what that does for us.

    That is a body controller output. The switch is blinking because either it is detecting a short or open. Most of the problems are in the mirror head itself with either corroded wiring or burnt out heater pads.

    Given the winter we’ve had up here in WI burnt out pads are very likely.

    I have a same problem exactly the same but I haven't got around to taking mirrors apart due to weather and temperature (northern Illinois). I may try my luck this weekend as we're going to hit 60's

    Flashing means there is circuit problem.
