My cruise control has recently stopped working. The green indicator light on the cruise control switch lights up, however, when I press the “set” button on the steering wheel nothing happens.
So far, I checked the both fuses. The set switch and the slip ring tested good. So according to Helm’s, I need to check the pinouts on the 14 pin connector that plugs into the cruise control box underneath the dash.
Turns out, I only have 13 of the 14 wires going into the 14 pin connector. I’m missing the Blk/Yel wire. Just looking for some advice, I’m stuck at this point. Can anyone take a look at the connector and see if you’re also missing the wire? TIA

Mine did the same thing, the light worked but no cruise control and since yours was recently working and you weren’t missing wires before. Check the little plastic piece on the pedal. That solved my cruise control problem. It looks just like the little plastic piece for the brake lights.
FCM: Good to know, it’s a 91.
I performed all the tests thus far according to the Helm’s manual. Checked fuses, verified continuity between the leads of the slip ring and the “set” switch on the steering wheel.
I haven’t checked all of the leads yet for the 14 pin connector, mainly because I noticed terminal 2 (blk/yel wire) was missing.
Checked terminal 1, the multimeter confirmed continuity to ground.
Skipped terminal 2
Checked terminal 3, and it didn’t pass the test…no voltage with the ignition switch ON. The only possible cause is an open in the wire. Next step is to check where the “LT GRN” wire leads to after 14 pin connector and check for continuity.
***Things worth mentioning…I disconnected an OEM alarm a while back, then shortly afterwards the cruise control wasn’t working…possibly related?? I noticed the main switch didn’t light up, so I replaced it with another c/c switch and it lights up like it should, however I still can not set the cruise.
Malformed: I’m not completely sure, however I don’t think so after briefing looking at the ICU wiring diagram. Ironically, I replaced the capacitors in the ICU (rear defrost was intermittent) right before working on the cruise control issue since both of the main electronics are located next each other…
1SickG2: I already looked at the back of the clutch pedal, the plastic stopper is still in place.
i would like to find someone that allready has the capacitors & etc to do mine once i get a second one just incase.
i allready dislike driving in the rain, driving in the rain with no int setting is even worse.
dont realy care about CC or any of the other stuff that doesnt work.
The light green lead runs from the CC switch to the brake switch and then is daisy chained to the 14 pin connector.
I would check the light green at the connector to the CC switch.
The black/yellow at the CC switch connector is from fuse 24 - 15A, [hot in run and start] in under dash fuse box, the fuse must be good and power must be getting to the switch as the indicator light turns on when you turn the switch on, you will need to know that there is output from the switch, so test the light green lead at the switch then at the brake switch.
The gray lead at the brake switch is the output, it runs to the 14 pin connector, it should have 12V+ on it, [from the light green] as long as brake is not stepped on, [CC shut down].:stare:94
FCM: I rechecked the terminal 3 (LT GRN wire) at the 14 pin connector and I had voltage. I guess I didn’t have a good connection with my multimeter. I continued the test as shown above, and once I reached terminal 6 (Pink wire) I didn’t have continuity to ground. Turns out that the connector for the clutch switch was disconnected. I probably forgot to plug it back in after uninstalling the oem alarm. Cruise control works perfectly.
I thought that with the clutch switch disconnected it would disable the car from starting though, guess not.
Malformed: I bought the capacitors for the ICM board from Digi-key. The were less than a dollar before s+h.
Btw, how do guys quote on the forums? I never figured that out…

It should not start, [crank] if the clutch interlock switch is disconnected, let me ask you this… will the car start without stepping on clutch?.:hmm:94
Mine is pretty much the opposite. Cruise works but the green light doesn’t. The word “cruise” lights up and all that. Not a big deal, but bugs me sometimes, as I’ll forget the switch is still on.

is the clutch switch the same for cruise as it is to start the car? the car does not start unless the clutch is pressed in, so i know that switch works.
what about the brake pedal switch? wouldnt the brake lights always be lit up if this was the problem for cruise control not working?
It is the same switch CIS, [Clutch Interlock Switch] but if you have CC the switch has 3 leads, [SPDT] to start the car the switch supplies a ground to the starter relay, when you step on the clutch peddle, when the peddle is not stepped on the switch supplies a ground to the CC module, stepping on the clutch peddle will cut the ground to the CC module, disengaging the CC.
The CIS could work for starting the car but may not work for the CC.:hmm:94
