Request for OEM Cruise Control information

Falcon 556 asked me for information about the OEM cruise control I purchased from Jeeps-R-us http://www.jeepsareus.com/Merchant2...JAU&Product_Code=CCCSK&Category_Code=CHEROKEE (also have a '99-2001 kit) and installed in a '98XJ.

I went to the web site and found the kit.
I am interested. Did the kit come with instructions?
Do you still have the instructions? If so, could you fax them, email them or just send them to me any way possible?
I'd like to see what is involved first.
Quite frankly, I might even use that knowledge to buy cheaper salvage parts.
My son is leaving for boot camp in a few days and it would be nice to upgrade his jeep by the time he returns.
My Jeep is a '99, what year is yours? It seems that from
99 to the end they made some changes.
TIA

It was a "piece of cake" to install... plug and play. Only 'fly in the ointment' was the nightmare-ish bout with pulling the steering wheel. Read: about the 4th entry down...http://www.naxja.org/forum/showthread.php?t=48171

The installation manual can be retrieved from:

I know Jeeps-R-us will not mind showing it as it could lead to more sales for them. Personally, I would go with a NEW kit and not get involved with a 'junk-yard-dog'. Keep in mind that the new clock spring alone for a c-c will run you $109.00. In my mind $249.00 for a spanking-new one is CHEAP compared to possible headaches involved with something a few dollars less! Everything is there.
I hope this helps you Falcon, and maybe someone else will benefit from it also.
Cheers!
 
Thanks for the post, I copied everything.
Last time I had to mess with cruise was on a 1987 XJ. I had a wiring
problem and had to check the whole system to find the problem (in the steering
wheel). During that time I remember that I had to disconnect the connector
at the control module.
Question, do the newer models have a control box, or are they controled by the PCM?
Thanks again.
 
Only things that come with the kit is: (1) New boot for the air bag[old one covered the switch sockets in both sides of the wheel/new one doesn't] (2) 2-switches and jumper(3) clockspring (4) vac control module that bolts to the inner right fender (5) instruction sheet. It is really "plug and play".

I dropped by a salvage yard and picked a steering wheel, clockspring and servo for $40.00.
Unfortunately the airbag connector on the clockspring is messed up. I am trying to decide whether to cut the connector from my original clockspring and solder it to the salvage one, or just get a new clockspring.
I checked the salvage yard clockspring for operation and continuity of all the wires and everything is good.
The only reason I didn't solder it already is because the airbag is a safety item and if something went wrong I might be exposing myself to liability law suits.
Hard to find an inexpensive clockspring. The price for the little plastic box with a flat ribbon and a couple of wires is selling from $110-250 depending on who's trying to screw you at the time.

"Aye matey!" (the very reason that I suggested just buying a new kit)

I didn't like the steering wheel that comes with the kit. This particular type is the same as the one in my XJ and the rubber part has separated from the steel core. The steering wheel had to be changed and that's what got me started thinking about cruise in the first place
I found what I think is a better design, looks like stiched leather. Came with the cruise switches and it was easy to pick up a servo. It made sense to continue with these parts.
I'll get some shrink tubing tomorrow and splice the connector, from my old clockspring to the salvage yard part. After all it is just a couple of wires.
 
Might want to lay your drivers seat down into the horizontal position the first time you put the key in and turn it, then count to 5, turn the wheel a couple of times both directions to make sure you didnt pinch any wires or other problem. Just a suggestion.... :)

i have a 90 xj with cc and it doesn't work i have no clue were to start to find the problem any suggestions......i did check the fuse and that is ok

Couple of things to try:

1. Check that the vacuum connections to the cruice control servo are intact - I think the servo's over near the battery, but am not 100% sure.

2. You may have fatigued wiring in your turn signal stalk. This is the case with me - I have to push on the wires coming out of the back of the stalk (facing the dash) before the cruise will respond to the "set" button and engage. Once it's engaged, it works fine. To fix this, get a new stalk. See your local auto parts store's HELP! catalog for the appropriate part.

Question about the vacuum connections.. I noticed mine was broken, does it need to be replaced with the hard plastic tube or will a rubber (flexible) tube / connection work?

Thanks...

I got all the parts installed, everything looks good, nothing works.
I checked the wiring from the steering wheel through the clockspring, all good, all the switches have the correct resistance values.
Checked the wires from the PCM to the steering and to the servo, brake switch, all good.
I don't get any power to the servo (pin 3) with the engine running and switch on.
It acts as if there is a fuse missing somewhere in the circuit. I have not being able to find a fuse specific to cruise.
At this point I need some ideas.
BTW the bag didn't blow :)
 
An update.
I did some more checking and found that the parts I used to convert came from a '98 not a 99 as I originally thought. I wonder if the switches (resistance) are different on the 99.
If the resistance changed between 98 and 99 then the PCM is not getting the right signal.
The servo might also be wrong.
I wish I had a parts catalog.

I bought a disk that has 97 and 99 on it (no 98). Apparently the 98 shares attributes in various areas with either the 97 or the 99. If that is correct, I suppose putting 98 parts on your 99 could in some instances be WRONG... don't know! Do you have a specific part in mind you want to cross-reference?
Is it possible that the 'repaired' clock spring is not making proper contact?

I have no doubt about the clockspring, the only thing I repaired was the bag connector. All the wiring tests good, individually and from one end to the other.
The switches test good according to some values that a guy posted recently.
At this point I suspect the switches may be good but not for the 99.
I don't know about the servo, it never received any power from the PCM.
I checked solenoid resistance and it seems OK.
Can you check switch and servo part numbers for 98 and 99?
Thanks.

Falcon check this out:
http://www.jeepsareus.com/Merchant2...JAU&Product_Code=CCCSK&Category_Code=CHEROKEE FOR '97-'98
http://www.jeepsareus.com/Merchant2...e=JAU&Product_Code=MB1&Category_Code=CHEROKEE FOR '99-'01

Would appear from those that the '98 Cruise Control is NOT THE SAME as in a '99!

I went there, something is different. Question is what?
Can't be the steering wheel, everything fits in it like a glove, and you know it is not the servo, has to be the switches.
 
Did a search and found a previous post with switch resistance values for a 99.
Those are the same values I was using to test the switches. The switches are good.
Another theory shot down.
 
Today I power checked the servo in my 99. With pin #3 hooked to 12V I connected ground to pins 1, 2, and 4. The solenoids clicked.
I then went to my 96 which is working just fine and pulled the connector from the servo, started the engine and turned cruise on. Even with the servo disconnected the green light came on. That tells me that the servo is not the problem in the 99.
I am now officially lost.
I have no idea why the cruise will not turn on.
I am starting to think that the PCM might not be capable of handling cruise.
Question: Did jeep use any PCMs in 99 that were not cruise capable?
How many PCMs are there available for the 99XJ?
