This is where I am. I have replaced all the vacume lines appart from the two little ones on the vacume pump itself. Did a vacume test on the regulator and it held vacume. Also when I turn the cruise control switch on I can hear a clicking under the glove compartment. I did have to replace the switch on the steering wheel which was a no brainer. How do I test the vacume pump or should I hear it come one when I turn the switch on???   Dave Thomas (Dthomas) New Member Username: Dthomas Post Number: 21 Registered: 11-2003 Posted on Monday, December 29, 2003 - 06:55 pm:    Did you check the cruise switch down by the brake pedal? Mine pops out every now and then.   Darryll Mills (Emnat) Member Username: Emnat Post Number: 42 Registered: 11-2003 Posted on Monday, December 29, 2003 - 07:00 pm:    What does it look like???   Darryll Mills (Emnat) Member Username: Emnat Post Number: 45 Registered: 11-2003 Posted on Tuesday, December 30, 2003 - 12:53 pm:    Dave I checked the switch and it was in. The only other things I can think of is the vacume pump or the cruise control box on the passenger side. I am not sure how to test either one of them.

If you search archives you will find how to test the vacuum pump by using jumper wires. I have never gotten my CC to work since it went out a year ago. I am down to replacing the ECU for the cruise but at $300ish I will use my foot for a while....   Corey (Discobro) Senior Member Username: Discobro Post Number: 276 Registered: 12-2002 Posted on Tuesday, December 30, 2003 - 05:43 pm:    In fact, here's the link: ../17/25591.html>   Darryll Mills (Emnat) Member Username: Emnat Post Number: 47 Registered: 11-2003 Posted on Tuesday, December 30, 2003 - 10:25 pm:    Thanks Corey, I must have missed that part of the search. I still can't get mine to work. This is where I am. Pulled the pump out and jumped some power to it, it ran fine and created a suction. How can you tell if it is creating enough suction?? I did pull the line off at the T going to the foot break and put my finger over the hole, I did this to see if the pump was strong enough to pull the regulator in, it did not and I am not sure if it should be able to either. The other thing I have done is replace the switch on the steering wheel, I hope I wired it correctly, there were two purple wires that I was not sure quiet sure about, I guess I could switch them around. Well I do want to succeed in this I just am running out of solutions, I guess I could get an 04 model but then I would not have a trail truck to play with.   dennis clifton (Flyor) New Member Username: Flyor Post Number: 16 Registered: 05-2003 Posted on Tuesday, December 30, 2003 - 11:28 pm:    Is the speed signal input getting to the control module?   Darryll Mills (Emnat) Member Username: Emnat Post Number: 49 Registered: 11-2003 Posted on Wednesday, December 31, 2003 - 08:23 am:    Not sure, where do I find the speed signal input?   Charles Allen (Callen229) Member Username: Callen229 Post Number: 103 Registered: 07-2002 Posted on Wednesday, December 31, 2003 - 06:30 pm:    Darryll I sent you an e-mail with an attached PDF for troubleshooting cruise control. Hope it helps. Charles
