VMM/ARC Problems...
Ok heres the problem.
I have recently bought another Sc (90 35th) and the problems started with the dimmer switch not wanting to go into high beam, this was an intermittant problem and when you pull back on it the high and lows come on as they should.
The other day the VMM and the ride control went out. I have change the relays,checked the 30 amp fuse in the dist center, check for power at the relays (ride control), and went as far as to change out the ride control ecm.
I have checked ground 100 at the column and have good continuity to the chasis. Check for power at the switch at the console and checked the bulb in the dash.
(1) Power at the switch = none
(2) bulb good
I know that the car isnt going into firm ride becuase of the feel and the absence of power to the relays in the trunk.
The 30 amp fuse in the engine compartment is showing 12vdc on both sides. The dash bulb gives no codes at all, nor does the diagnostic connector have any voltage.
I have another 90 model here so part swapping is not a problem, but personally I feel that is is something so simple that I will end up kicking my self in the end.
After using a snapon mt2500 to scan the car it has no codes on the engine ecm but will not communicate with the ride control ecm.
One last thing to ponder is that the cruise or horn does not work and that that the prior owner had the premium stereo pulled out and put an aftermarket on in without any amps (the original wires have been cut) no problem cause I have another for parts when I get around to it...
Ok guys and girls jump on this one becuase it has me totally confused and as I said before it is probably something very easy but I am overlooking it....
Thanks
P.S. I have access to all the wiring diagrams for this car and have traced out everything that I can think of, which is what I have mentioned above.
