Why does my defroster on my rear window not work?
If it lights up, the grid is getting power. Grid Breakage Test: If power is getting to the grid, your defroster problem probably is due to a break in the painted grid. This is especially likely if your defroster works on part of your rear window.
What to do when your defroster doesn’t work?
Touch the grid every three inches or so to find the break. It’s normal for the light to be brighter in some spots, as long as it lights up. If you find a break in the circuit, move the test wire back and forth until you know exactly where it stops working.
Why does my windshield wiper keep working intermittently?
If the problem is not in the switch, then there could be a bad relay in the circuit (if so equipped), loose fuse, bad ground, and/or the motor could have a bad (intermittent) connection on the armature. Also, of course, you could have a combination of these electrical faults. It’s easy to diagnose.
Why do my intermittent wipers not wok on intermittent setting?

What happens if there is no power to the wiper?
If there is power, the motor is bad. If there is no power, although the motor could “still” be bad, you first want to trace the circuit back to the power source to figure out where the break is. Once the circuit is fixed, of course if the motor still doesn’t work, it’s condemned and replaced.

One of the quickest indicators that a problem exists with the intermittent wiper relay is when the wipers are not intermittent and only work at one speed. The relay switch sends an electrical signal to the module that controls the operation of the wiper motor and gears inside.
What to look for in a Ford wiper wiring diagram?
Then check for power at the relays. Follow the Ford wiper wiring diagram and check for power at the relay contacts and control coil. Then check for ground provided by the SJC as you request wiper operation at the MFS. Finally, check for good ground conditions at the MFS, SJC, Wiper motor and washer motor.
What is the wiper speed switch on a Ford?
The Ford wiper control system on late model vehicles is completely different than anything you’re used to in the past. Examine the Ford wipers wiring diagram below. First, notice thathe wiper speed switch is now called a multi-function switch (MFS).
What causes a wiper fuse to burn out?
That way, if the motor is overloaded for any reason, the fuse will burn out first, instead of the more expensive wiper motor. If the wiper motor fuse burns out, check for any obstructions that may cause the motor to be overloaded.
Why does my windshield wiper not work when I change the pivot?
A nut tightens onto the pivot stud to hold the wiper arm tightly to the pivot. If the nut is a little loose – which is common – the wiper motor will turn the pivot but the wiper arm will not move. You may see it slightly move when the wiper direction changes, but it does not wipe the windshield.

Why is my intermittent wiper not working on my Jeep?
Since your wipers don´t go into low speed continuous mode, it seems that the rain sensing module is working, but not sending a wipe command.

Why do my wipers go into low speed continuous mode?
If the BCM doesn´t get ANY signal from the rain sensing module, it will switch the wipers into low speed. If it does get a signal, it waits for a wipe command from the rain sensing module. Since your wipers don´t go into low speed continuous mode, it seems that the rain sensing module is working, but not sending a wipe command.
If the windshield wipers function on high and low but do not work on the intermittent setting, then your intermittent wiper relay may be faulty.
