I've already replaced: C/C motor/cable pulley under the hood, C/C on/off switch, Resume/Accel etc switch on wheel, kill-switch on the brake pedal, C/C module next to the steering column. I've also tested another steering wheel hub/adapter - nothing. please help. i have a 91 GXE.

Symptoms: the C/C power switch on the dash gets power and the green light comes on, but C/C never engages.

Does it work intermittently? I noticed about a year and a half ago that my cruise control stopped working, but then after a few months it randomly started working again, and has been working ever since

Is the unit itself under the hood "loose" by any chance? I remember my brother retrofitted cruise control into his Civic a few years back, and it didn't work even though he was sure it was all wired 100% and everything. It turned out to be something goofy with the unit itself under the hood not being level. He fabbed up mounting hardware for it and it was kind of angled, and he found out it would only work when it was nearly perfectly horizontal with the ground

No, it doesn't work at all. I'll give that leveling idea a try, but again I've already had 2 units in that car. Plus the way the unit is screwed in it's kinda hard to position it any other way.

My cruise recently stopped working and it ended up being a loose fuse (I think). I checked the relays and fuses multiple times but I finally got fed up and pulled all the fuses in the fuse box and put them back in. The next thing I new my cruise was working again.

Same problem here

The Cruise control button will light up but I don't get the light to turn on on the inst, panel

Maximus94

Just to clarify... Did you guys check both the fuses and relays?

I know the relay is under the hood by the battery, but where is the ASCD fuse? I checked all fuses in the fuse box to the lower-left of the steering wheel - all are good.

Maximus94

The ASCD shares a a few fuses, one of which is the horn. Since you checked all the fuses, does your horn work? My horn did not work when my cruise quit. If it does, check the ASCD relay and make sure that it is getting twelve volts.

The horn def works, I'll have to get a voltmeter to the relay though. Any other specific fuses to check or anything else?

Maximus94

I looked up ASCD in my service manual (1994) and see that the system is connected to 7 fuses on the panel (left of driver's seat). This is the only fuse box that I know of.

Left column:
10A 5th from top
10A 7th from top
10A 8th from top
15A 11th from top
10A 13th from top

Right column:
10A 7th from top
10A 10th from top

Once you see if the relay is getting 12 volts or not, you can tell if the problem is before or after the relay.

thanks for that info, I'll check it out later tn at home. what is the order of the power flow to the C/C system? eg if the relay is getting less than 12V what does that imply?

Also, in what section of your 1994 FSM did you find that info? I have a 1989 FSM that I use for my 91.

Maximus94

Power goes thru the fuse box before it gets to the relay.

It's in the EL section.

Mine stop working too, its not turning on the green ligth at the on/off button . Where is the fuse / relay ?

See post # 10 for the fuses. The 2 relays for cruse control are in a box in front of the battery. The 2 you want to look at are the ASCD hold relay and the Inhibitor relay.

Well i have a 89 and have had cruise problems on and off for over 5 years.
Always the main switch on the dash will power up but sometimes the cruise will not activate when you hit the steering wheel buttons. When it did work it would randomly drop out of cruise while travelling along sometimes after a small bump etc. Used to work well cruising on the freeway.
Last month the speedo started giving erratic speeds and quite often would stick in one spot no matter what speed you did.
Luckily i had a spare from an instrument cluster i got off a wreck several years ago.......Swapped them out and the cruise control has worked flawlessly since and i use it all the time. Seemingly the speedo unit processes signals and send them to the ECU ( which is a given) and cruise control units. Mine also has the sonar electronic adjustable suspension and that used to have lots of problems and it also has been working correctly since the speedo was changed! Who would have thought of that eh!!! Vee
