Heated mirror question

Postby egagnon086 » Thu Mar 02, 2017 2:00 pm

So looking at this diagram, It would appear that for the mirrors to work, you need good power, a good fuse, good grounds, then press the button, and something needs to happen at the HVAC controls.

Anyone have any idea what needs to happen at the HVAC controls for this to work. Does it need to be on defrost?

I don't have heated mirrors, but I say NO - nothing needs to happen to the HVAC control.

I read it simply that the HVAC control shares the same chassis ground wire and grounding points as the mirror heaters.

That's just it the, control lever doesn't ground to anything. There is a switch on the defrost position so I figured that was it. But it doesn't seem to change anything when lever is in that position.

Why do you think something needs to happen to the HVAC controls to make the mirror heaters work? Isn't just a case, as you first said - "good power, good fuse, good ground, push the button" and it should work.

Does that not happen? Or were you expecting the HVAC control on DEFROST to also heat the mirrors? Do you have the good power, good ruse and good ground?

I'm not getting power when I switch it on. Power to fuse. But for some reason the mirror button doesn't light and mirrors don't defrost. I'm about to straight wire them and ground out this relay.

on my 98 trooper, I do not have to have the heat in defrost for the heated mirrors to work, however they also do not shut off unless I press the switch to turn them off.

A simple jump wire on the back of the mirror heat switch will turn them on. I installed a trooper mirror heat switch in the switch blank next to the heater controls.I just back probed into the existing switch. I also have a 98 amigo.
When in doubt gas it!
