RF600 Posted May 12, 2012 Share Posted May 12, 2012 I have a 95 Pathfinder with a m/t. I am doing the checks like the manual says. I jump all 4 wires and the cruse wire pulls. Next the manual says the cruse wire should return back in 50-60 seconds. Mine goes back immediately. So I think that the actuator pump is bad because it doesn't hold. Is that correct? I put vac to the actuator ( the pod with the diaphram) and it will pull the wire and hold. The switch will illuminate. I checked the other switches and everything is good. The cruse did work off and on before. Link to comment Share on other sites More sharing options...
Slartibartfast Posted May 12, 2012 Share Posted May 12, 2012 Leak between the pump and the actuator? Link to comment Share on other sites More sharing options...
RF600 Posted May 12, 2012 Author Share Posted May 12, 2012 The hose is good between the pump and actuator. I can blow into the hose and hear it coming out of the pump. I would think being a pump it shouldn't be like that? Bad diaphram in the pump? Link to comment Share on other sites More sharing options...
Slartibartfast Posted May 13, 2012 Share Posted May 13, 2012 Possibly... it's gotta come out somewhere, it could just be a stuck valve. I'd probably try tearing into the pump to look for dirt or bad rubber bits. Link to comment Share on other sites More sharing options...
silverton Posted May 13, 2012 Share Posted May 13, 2012 How well does your horn work? It could be the funky thinks that make the electric contact behind the steering wheel. three spring loaded posts ride in channels. This happened to my truck not long ago. the dialectric grease collects all the dust/dirt/grime and no longer lets electricity do its thing.

RF600 Posted May 13, 2012 Author Share Posted May 13, 2012 I'm pretty sure my horn works. The last time I used it was a while back. I will probably open the pump up and have a look. Doesn't look like there would be much to it. Link to comment Share on other sites More sharing options...
RF600 Posted May 14, 2012 Author Share Posted May 14, 2012 The horn works fine. I pulled the pump apart as far as I could. There is a diaphragm that I can't get to unless I break the housing. Would anyone be willing to check their pump for me? Pull the hose off of the actuator pod and blow through it. I have not seen any pathfinders at the yards in town. I know there are some in the next town but that is ~30 minutes away. I don't want to waste the gas unless I have to. Link to comment Share on other sites More sharing options...
Slartibartfast Posted May 15, 2012 Share Posted May 15, 2012 Just opened mine up, pulled the hose off the actuator and blew into it. No resistance, like there's not even a pump there. I tried sucking on it too, nothing. I imagine the pump locks up a valve or something when it gets going. (I can't imagine it as a sealed unit in an engine bay... too much temperature variance, thus pressure variance... probably.) The one thing I did note was the cracked and hardened hose... at this point I doubt your hose is bad, but it couldn't hurt to check. Of course, I've never actually used my cruise control. My dad said he got it fixed when we got the truck, and IIRC he tested it, but my commute's too short and hilly to bother with it. Anyone with known good cruise want to chime in? Given that the 'resting state' of the pump appears to be wide open, I'm guessing that the 50-60 seconds are controlled by the cruise control circuitry... maybe check the wiring? Or, as Silverton said, the sliders behind the steering wheel. My horn worked fine until one day when it didn't... didn't take the wheel off (couldn't figure out how to remove the horn pad) but still got loads of crud out with some alcohol and a q-tip.

msavides Posted May 15, 2012 Share Posted May 15, 2012 My cruise control works but it does something strange. As soon as I turn on my blinkers its cancels. Link to comment Share on other sites More sharing options...
RF600 Posted May 15, 2012 Author Share Posted May 15, 2012 Thanks Slartibartfast for doing that for me. That means I can rule out the pump. Well I guess it is time for more trouble shooting. Gotta love it. I did pull the cruise switches off at one point and clean them up. That didn't help. Link to comment Share on other sites More sharing options...

msavides Posted May 15, 2012 Share Posted May 15, 2012 (edited) Yes I do. I am not sure if it is the leds or the electronic blinker relay. Edited May 15, 2012 by msavides Link to comment Share on other sites More sharing options...
Towncivilian Posted May 15, 2012 Share Posted May 15, 2012 You need one incandescent bulb somewhere in the circuit to draw enough current, otherwise you get the issue you describe. I don't think your 91 has a third brake light, right? Link to comment Share on other sites More sharing options...

Towncivilian Posted May 16, 2012 Share Posted May 16, 2012 If it's possible, put an incandescent bulb in the third brake light and it'll fix your cruise control. Link to comment Share on other sites More sharing options...
fixitman Posted May 19, 2012 Share Posted May 19, 2012 I'm with pacnw. When I first got my Pathy the cruise control didn't work at all and I noticed a scraping noise when I turned the steering wheel. Sure enough the contacts under the wheel were completly worn out and not making any contact. Easy thing to check. Link to comment Share on other sites More sharing options...
RF600 Posted May 24, 2012 Author Share Posted May 24, 2012 I have to put outer boots on the front axles so I will take a look at that also. Hopefully this weekend I can get to it. I do miss having cruise control. Link to comment Share on other sites More sharing options...
Slartibartfast Posted May 24, 2012 Share Posted May 24, 2012 BTW, I used my cruise control yesterday and today with no difficulty... so the operation of my pump (and yours) is correct. Link to comment Share on other sites More sharing options...

lint Posted May 25, 2012 Share Posted May 25, 2012 Great. Now that I've been reading this thread, my cruise stopped working. I think you jinxed me. Link to comment Share on other sites More sharing options...
RF600 Posted May 27, 2012 Author Share Posted May 27, 2012 I pulled the steering wheel off and the 3 contacts were not making contact to the wheel.. I loosened up the clamp that holds the switch and there was a little up and back play. I pulled it forward and tightened the clamp back down. I have not had a chance to drive it yet and see if the cruise works. All 3 contacts are touching the steering wheel now. Link to comment Share on other sites More sharing options...
RF600 Posted June 3, 2012 Author Share Posted June 3, 2012 I had a chance to drive the Pathfinder and the cruise works. Even the resume. So I will have to do like others have done and "extend" the buttons. Link to comment Share on other sites More sharing options...
