thomasmcc Posted February 15, 2007 Share Posted February 15, 2007 Considering all fuses are good, what is the most likely reason why one of my side view mirrors ('98 ES) does not heat up? Tom Quote Link to comment Share on other sites More sharing options...
blk_on_blk Posted February 15, 2007 Share Posted February 15, 2007 Considering all your fuses are good, then you've probably burned out your heating element. They are resistive heating elements, and thermal fatigue tends to make them fail over time. They just have a finite cycle life. The best way to check is to disconnect the heating element (should be a two-wire heating element) and use a multimeter to check for continuity (setting the meter to resistance (Ohms)). If you get an 'infinite' reading of resistance, you've burned open the circuit and the heating element is dead. If you get a decent reading, then your element is probably okay.
