1992 Cadillac Deville Repair Question
1992 cadillac deville
Sorry cadieman I was using my phone and I accidentally pushed the flag for review button. I didn't mean to.
Ok so I did jump the gray and brown wires. I took a piece of wire put one on the wire strip and one on the other and it made no differance.
That would indicate the brake switch is not the cause of the problem.
We have been going around in circles and don't seem to be getting anywhere.
I did not go through all the post completely and might have missed out something so fill me in if necessary.
Is the Orange Indicator Light now showing when the switch is turned on? This light must be indicating so that the cruise control system is in standby mode for it to work when cruise speed is set.
No the orange light is still not on. Me and cadieman have checked power at the switch their is power going to the switch. I also tested both sides like cadieman wanted me to and i had power. I turned the car to the run position and pushed the off an warmer and let it go through then I turned the lever on and it shows E. 7.0 when I push the brake it switches from E.7.0 to E.0.0 same thing if you try to set it or resume. We just tried jumping the grey and brown wire on the brake switch. It made no difference the light did not come on.
You should get that resolved first as that is the main on off for the system. Without this light turning on, the cruise is never going to work, unless the problem is only a faulty bulb.
When switch is turned on, Check the Brown wire at brake switch for battery voltage.
Ok it had 11.5 volts I ground the back probe to metal and put the red probe on the wire.
The 11.5 volts indicates pwer is getting there.
There are 4 wires at brake switch, one should be hot at all time and one more only when the cruise control switch is turned on with ignition on. Is that what you are having?
No none of them are hot when the car is off. When you turn the cat on then it gets voltage at all of the wires. Their are another set of wires on the brake switch. Orange and two light blues that are connected together in the switch. The orange has 11.5 volts and the light blue has no power. I also tested the cruise switch above the brake switch and everything their has 11.5 to 9.5 volts.
check for voltage on the pink wire at the lever connector with the key on.this is what controls the power to the lever.if no power is their check # 7 fuse 20 amp.

Hey guys sorry I am back in the hospital again. They think I have Stevens Johnson's disease. I looked like a lobster yesterday I was red red and had no energy and my skin had hot heat coming off of it and my eyeys were teice the size the should have been. they were thinking of sowing my eyelids shit so nothing bad would happen. So they are giving me steroids to cure this. A few people have died from this but I know I can pull through it. I will work on it once I get better. Maybe Friday at the earliest. Thanks.
