Wifes Ascenders wipers won't turn off. The intermttent feature doesn't work either. The speed control does work, and the washer works, but they just won't stop. Any ideas?
Do you
have the same problem?

Hello nstfx

Replacing the relay # 42 in the fuse block underhood will take care of the problem.
(I'm sending this diagram to your email)

I replaced the relay, and the problem is still there. They still run even with the relay removed from the fuse block. What should I check next? Thanks, Karl

Hello instfxr

In the fuse block rear,remove the front wiper fuse 33. it is an 25 amp.The wiper should stop
if the wiper stops, trace the yellow wire all the way to the connector.
There must be a short to ground somewhere on the way to the connector or in the connector.Let me know if the wiper still does not stop.
The fuse is hot in "acc "or "on"
"That relay was the washer relay only.sorry Sir"

I checked, and fuse 33 is for the ABS. It's also 60 amp. I looked at the diagram, and there isn't anything obvious for the front wiper. There has to be one somewhere for the wiper.

Hello instfxr

You have look in the fuse block under-hood.
Look in the fuse block rear, it is a 33 with 25 amp. It is for the window wiper.
The fuse 33 with 60 amp under-hood is for the ABS.

Sorry about that. I didn't realize there were 2 of them. I'll get out the owners manual and find the other one.

Hello instfxr

Trace the yellow wire to the connector. Look in the connector for corrosion that may causing the short.

Before I remove half of the interior, wouldn't a short cause the fuse to blow?

yes a short can cause fuse to blow.
There are 2 kinds of short circuit, a short to power and a short to ground. A short to power can occur within a component or between circuits.
If the short is within the component, the component will not operate properly or may not operate at all.
A short to power between circuits usually result in components operating unintentionally.
This can be due to worn or burned wiring insulation or corroded connectors. Carefully inspect all wiring and connectors in the circuit for damage.
On the other hand, a short to ground will usually cause a fuse to blow as soon as it is installed. However, if the short is on the ground side of the load but before a grounding switch, the fuse will not blow but the component will not turn off. In this case remove the fuse and connect a test light in series between the fuse terminals. If the light comes on, there is a short to ground.
Start at the circuit load and trace the wire to back to the power source.
