Rear defrost - any way to test?

[tsi1991awd]

So yesterday morning my rear defrost worked just fine. And then when I was coming home from work, it wasn't working. It baffles me that it would stop working and then later in the night, my oil pressure gauge stopped working

Just my luck. So is there any way to test it and see if it actually went out, or do I just have to buy another module?

A test light or a volt meter, tap into the wires and see if you are getting power and see where it burt out. also check your fuses.

A test light or a volt meter & check your fuses.

+1

pull the two leads from the defroster put your volt meter on them, turn on the defroster up front & see what voltage you're getting 12+/- 2. (check your fuses if no voltage) Then turn the defroster off, remove the leads from the spade connectors. Switch to ohms & put the leads on the tabs from the defroster on the rear glass. should get some sort of reading, not "open." I've actually been wanting to do this, not because the defroster's broken, but because i'm going to have the tint redone & want to ensure when the shop pulls it off that no defroster lines are damaged.

good luck.

Ill give that a shot when I get home. Is the defroster fuse by the drivers kick panel or under the hood?
