Defrost not working....any ideas?

Post by shebuilt »

Hello all. Been some time now. Of course we are on the way here in LA for a cold and long winter. My back windows won't let me see a THING!

The light is lit but defrost isn't working.

Any thoughts forum?

The grids wear out from oxidation and just being cleaned. Ohm it out, it should be under 5 ohms at the highest. Check voltage too of course, but it's probably a bad grid. If you're up for the work you might be able to find one in a yard out of an E28 that's still good, but ohm it out too. E28 would be an exact fit.
