I have a 2000 Taurus SE-S with Duratec. My rear defrost is not working. I do have an aftermarket Metra kit for the HU. My rear defrost recently stopped working. No light on the button and no click from the dash.
I can't seem to get the relay to make that click noise when I press the button. I am trying to figure out if the relay itself is faulty.
I tied a wire into Relay Pin #85 & #86. I hooked up the multimeter and I had 3mV steady as well as .03mA. I also got a 92Ohm reading.
Then I tied a wire to Relay Pin 30 & 87. I got 13.84V and 3.39 mA. 0 Ohms. The readings were slightly lower when I turned the car off.
When I tied 30 & 87A there were no discernible differences between 87 and 87a.
Are these readings normal? ARe there other tests I need to run?
Nothing happened to the readings when I pressed the defrost button.
pull the relay out and get a 9 volt battery. look at the relay and you'll see a diagram of the insides and the pins are numbered. use an ohmmeter over the two switch pins and put the 9 volt over the two coil pins. should read near 0 - .1 ohms. and you'll feel/hear it click.
Ive only checked two of those fuses...where is the other 10amp?
According to my manual,
Fuse #7 is the 40 amp Rear Defrost Grid Feed.
Fuse #12 is the 10 amp heated mirrors and Rear Defrost Switch.
Fuse Position #9 is the relay itself.
Where is the other 10 amp fuse? (I'm assuming #207 is the 40amp and 212 is the 10amp mentioned above. My fuse position #32 is ABS, DRL Relay Coil, Speed Control Actuator, Traction Control Switch, AC Heater Selector Swicth, Blend Door Actuator, Brake Shift Interlock
