Well this morning it was pretty frozen i we iced the truck etc drove maybe 5 miles went to clean the screen using the washers but the wipers froze. now i only have wipers working on fast no intermittent and no washer/wipers when the washer button is pressed anyone had this issue? Is there a fuse for this part of the circuit?? Thanks

If the wiper are coming on the fuse is good. There is a relay in CTM that comtrols delay. I'm not sure if you can fix the CTM. Might be a fuse for the CTM.

Sorry whats the CTM? Wiper fuse is ok and i have wipers working on fast just no intermittent or washers

Central Timer Module. It above your throttle foot in the dash. Near the power point plug. CTM takes can some cab functions like delay wipers, security alarm, etc.

Hmm strange just been reading about the CTM door locks etc all work but i did read there is 2 fuses for the CTM i wonder if that is my issue 

Let us know what you find as I'm interested as well. Fuses your looking for are probably in the fuse panel and can be tested with a test light. I think everyone knows that, but It will also hurt an ohm meter if any of the circuits are on while using that setting, so you should have batteries disconnected if you use that setting on the volt meter.

Ronnie,

I have attached the electrical diagrams from a 2001 for the wipers.  Most likely it is your multi function switch.  But it could be the CTM too.  There is a good diagnostic chart in the manual also.  Here is a description of the operation:

 

• Continuous Wipe Modes - The two-speed
wiper motor and the internal circuitry of the multifunction switch work in concert to provide two continuous wipe cycles, low speed or high speed.
• Intermittent Wipe Mode - The internal circuitry of the multi-function switch, the CTM, and the
wiper relay work in concert to provide an intermittent wipe mode with multiple delay interval selections. On models with a high-line or premium CTM,the CTM also automatically adjusts each manually selected delay interval to compensate for vehicle speed.

 

All of the power comes from fuse 6  in the panel by your driver door (called the junction block)  So if any part works the whole system has the potential to work.

 

When you turn them off do they just stop or do they go back to proper position.  (this would tell us if the park switch is working.)

Its odd that you lost low speed too.  The power for low speed (and high speed) is a direct signal from the multifunction switch.  red/yel and brown/white feed low and high speed directly ignoring the CTM. 

 

The park switch in the wiper motor is an important part.  I think the CTM will never reset without seeing the park switch. 

 

Hope this helps  GL

Thank you very much the wipers do not park they just stop wherever they are when switched offf

Yes the wipers just stop and do not return to the park position 

 

Thank you for the drawings

Ronnie,

 

The wipers SHOULD stay powered until it trips the park switch.  So something is wrong there...

I have not played with the chrysler wiper motors, but the GMs you could get into and see how the park switch worked and test it out.  I see you are in UK, so i am guessing a new wiper motor is not an easy trip to the autoparts store.

 

Be careful.  The diagram I attached is a 2001.  The wire colors may be wrong, but I think you could use it to test your system.  you will at least be able to see if you are getting the proper 12v signals on the high and low commands.

Here is what I've got for wire map as well.

Wiper motor failure. The park reed is most likely damaged. Most likely when you try turning them on and then switch then off but the motor couldn't reach park again. The motor was in a locked state and most likely burned the park reed. 

 

 

When my wipers quite parking it ended up being a wiper motor.

Well i now have low/high speeds and washer fluid is now working but i still have no intermittent (relay does click every 2 seconds or so when intermittent is selected) wipers do not park still and i have no annoying ign on chime etc now?? ?

Gamble. Try changing or trading the wiper relay out with something like the horn. Try again.

Tried that already i would say the relay is ok because the delay on the relay clicking in and out. I suspect wiper motor but its odd I lost that chime for the ignition.. I unplugged the CTM to see if it would reset but no joy.

Well this is where I'm at all fuses tested ok

 

3 wires have continuous 12v to the wiper motor when hi/low is selected 1 wires drops to 4 volts the other 2 drop to 0 volts... 

 

When intermittent is selected all 3 wires stay hot regardless of the relay clicking in and out.

 

Is this because the park switch isnt working in the motor? 

 

I only had a quick 5 min look due to snow dark and minus 2 or 3 celcious

?

 

Also i unplugged one of the ign fuses and the chime started inside for one reason or another but not too interested in chime working or not i just like my wipers working correctly.

 

Any more help would be much appreciated thanks

Forgot to add something

Kinda have the same thing going on with my 98. I have L/H and it goes to park but no intermittent. My washer works but have to have the wipers on L/H to clean the wind shield. Ive swapped relays with no luck. I pulled the motor and transmission out and tried to get into the motor but had no luck.

I know when I got my new wiper motor, it said something and instructions about cleaning a ground that can cause intermittent issues. I believe that ground is somewhere on the motor or buy it.

If you turn on the wipers when the wipers are frozen to the windshield you end up welding the park switch and you lose the park position. The park function is related to the intermittent setting. If you are good enough you can sometimes open the motor housing and break it lose. I have done before this but only half of them survived.

Yeah I've ordered a motor surprisingly cheap to buy!

Went to change the motor today wiper arms are froze solid the little pin slides out but the arms will not leave the spline any tricks on getting them off?

Ronnie,

 

I have had them stuck before too....   Spray a bit of penetrating lubricant in there.  With the lock in the out position, I use some small pry bars, and slowly and carefully put some upward pressure on each side of the wiper arm. Wiggle, pry, wiggle pry, spray more oil.  Eventually it will slide off.  Some of the issue is the wiper arm is to one side, so when you try to pull, you make a rotating movement and the splines don't want to separate.  The trick is even parallel pressure.
