ZJ clock spring, cruise control, windshield wiper ?

I've been using our 1993 5 speed ZJ ever since Mom retired it. She bought it new and it has never been out of the family. Somewhere around 150k miles the cruise control stopped working, completely dead. The fuse is good so I just assumed it was the module. The other day on the XJ side, I read a post that suggested the clock spring was the cause for a non-op cruise control.

I have also been having issues with the windshield wipers. They work in slow mode or fast-delay only, most of the time. Occasionally all modes work normally. The multi function switch was replaced with no change.

Is it possible that the clock spring connection could relate to both issues? Where is it located and how do I service it?

Reliable Red has 259k miles so far with no indication of giving up. I would just like to fix these quirks.

the wipers is bad solder joints in the pulse wiper module. there's a few write ups around here about repair for the early model zj's. the later model zj's have that module built into the motor.

the cruise could be a bad brake switch, bad switches on the wheel, or bad clock spring. does the cruise light come on? is the air bag light on?

There is zero response from the Cruise. It appears completely DOA. The air bag light is not on, though I am fairly certain it lights up on start up with all the other check lamps.

Good to know info on the windshield wipers. I'm looking forward to finally having that fixed. I should have bought stock in Rain-X with the frequency in which I have kept it applied.

Does the 93 model have a light for the cruise control? If it does, I have never seen it and mine works fine.

never seen a vehicle that didn't have a light. even my friend's 79 t-bird had a light for cruise.

Check Fuse#20 (10 amp) in Fuse Block located at passenger end of dash.

Check for proper clock spring continuity and cruise switch functionality...
  1. First disconnect the negative battery cable, turn key on, wait a few minutes for circuits to discharge
  2. Remove steering column lower shroud cover
  3. Remove the clock spring connector (white)
  4. Check continuity with an ohmmeter between Clock Spring Pins.....


Switch OFF
Pins 1 & 4 (YL/RD & WT/LG)

Switch ON
Pins 1 & 4 (YL/RD & WT/LG)
Pins 1 & 2 (YL/RD & BR/RD)
Pins 2 & 4 (BR/RD & WT/LG)

Switches ON and SET
Pins 1 & 2 (YL/RD & BR/RD)

Switches ON and RESUME
Pins 1 & 3 (YL/RD & WT/RD)

(wire colors listed are on connector side)
