It worked last year and now we are starting to have cold dew mornings. Well it's not working
Push the button and light comes on at the dash...... Unplug wire and Check voltage on the plug going to tang on the pasenger side 12.7 volts. Plug it in and check tang again 0 to .5 volts. Clean tang and plug back in and have 12.7 volts on tang. Good power coming too window.
Go to other side (Driver) unplug and check tang 12.7/13.5 volts..... Good power across the window...Then as soon as i plug (Driver side) back up and check tang back to 0 to .5 volts. Cleaned tang and plug and same results.
Cant check to see if it works till it fogs up again.
Never been an electrical guru. :facepalm: Am i missing something?
