Alright. I installed the cruise control equipment on my car.

S4 N/A with a vacuum driven cruise canister. ECU near left footwell, and switch in dash. All mounted and ready to go....or so I thought.

When I turn on the lights, all my switches light up except the cruise switch. If I push the switch up, it lights up. If I push the "Set" button, it will light up. If I push the lever up and then push the "Set" button, it kills all my lights.

I am pointing my finger at a bad switch.....what do you guys think?

If someone in MI has a spare switch and Cruise ECU AND is willing to let me borrow/buy the part I need (borrow to test, buy to own ), I would greatly appreciate it.

Huh??? what lights up??? all the switches in the car???

what is lighting up??? your post makes no sense.

There are three bulbs in a Cruise switch. The Main (which says Main when the little push button is pressed on), the cruise (which says Cruise when the cruise system is activated) and the dash lumination which lights the switch so you can see the writing (other than Main and Cruise) at night.

Please describe exactly which one(s) is/are lighting when you are trying to use the cruise control.

The interior illumination works fine on everything except my newly installed cruise switch. It will not light up, like no power.

When I push and hold the set button, the switch will light up until I release the button. If I push the switch into the resume position (up), it will also light up. If, while holding in the resume position, and then push the button it will turn off all the interior lit switches (turn, headlight, wiper).

Is that better? Sorry to be vague in the first post.

Also, the cruise control isn't working. This is the main problem I have, the lighting is secondary, but I am assuming that the two are correlated.

I am assuming that by that, you mean that the indicators that normally light up with the parking lights on, such as accell/decell/set on the actual lever itself do not light up???

what lights up??? the word cruise, the word Main, or the words and main button on the lever???

This is the correct switch for the series right??? You are not trying to use a S5 switch in a S4 car, right???

Yes, the accell/decell/set indicator lights do NOT light up when I turn on the running lights.

When I push the button that normally sets the cruise, all the lights turn on. The same effect occurs when I push the switch up into the resume/accell position. Once I release the switch from either position, the lights go back out.

I am assuming this is the correct switch for the car, the wiring harness in my car (S4) plugged into the switch without any problem. Unless Mazda changed the pin-outs on the switch between series 4 and 5.

ALL indicator lights = gauge cluster, wiper switch, turn signal switch, headlight/rear defroster switch.

They all will go from red to no illumination at all. The cruise control will NOT engage at any speed (40-70 mph)

Yes, the two series switches are different and are not cross compatible. The plugs are the same but the workings of the switches are different.

Did you swap the cluster bezel with a S5 one? The S5 switch only mounts to a S5 bezel.

If it is the correct switch for the correct series wiper harness, then the switch is big time messed up as it should not be lighting any lights in the car other than the Main, and Cruise indicators on the actual switch itself.

Take this jpg:
https://www.rx7club.com/forum/attach...postid=1022159

And ohm out the wires to the switch FROM the Cruise Control Unit near your feet.

The key is to pull the plug off. Put your meters neg lead on a good ground. Put the meter on ohms. Put the pos lead on the LR wire. Lever the Cruise switch up and observe the meter. YOu should now see a ground. Let the Cruise sw relax. The ground should go away.

Now get on the LW wire. Press the Cruise sw to Resume. You should now see a ground on the meter. Let the switch relax. Now you should not see a ground.

Now get on the GO wire. Press the Set switch in and hold it. You should see a ground on the meter. Let the Set relax. Now there should be no ground.

Let us know what happened.

Now get on the RG wire. Put the meter on volts. Turn the cars light switch to on. You should see 12v approx.

I *think* there is a difference in some models switch. The wires CAN be swapped around in the plug at the switch is this is the case.

You NEED to ring out the wires from point to point to confirm that the wires are in the right holes. I'll try to jpg the plugs showing where the wires go. That might happen/might not. This site is hard to jpg squat to anymore (over a year now.).

Cruise plugs:


OOPS. Try the next post. I made an error on this one.

HAILERS

Pluggzzzz:

HAILERS

The idea here is to unplug the plugs. Look at the backside of the plug where the wires enter the plug. That is what the jpg above is looking at. Now compare what you have on your plugs compared to what is shown in the jpg above.

If you find a wire color or two that don't match....write back. IF they all match, ring out the wires point to point and do the ohms check mentioned in the first post.
