 Heater not working
Yesterday I was going to my sisters for dinner and temp was low 50's so I wanted to use heater. To my surprise the ac control knob lights are not working, yet the a/c vent and circulation buttons light up fine. A/C turns on and works to spec but the heater does not engage or turn the heat on.
I also noticed that my turn signal was not making a clicking sound but was working fine, few minutes later it started working and making the ticking sound again. Funny thing is that my heater lights also came on on the way home but the heater was still not working.
So my question is are these symptoms related to a relay or a fuse? Any input is appreciated. __________________  |
