Hi Everyone,
With the weather much warmer these days I thought I would go after fixing some electrical problems on the Truck.
1) Approx a year ago the power Door Locks stopped working
2) Approx 6 months ago the daytime running lights stopped working.
3) Approx 2 weeks ago all of the interior courtesy lights stopped working.
I thought I would go after the Door Lock problem first since it's handy to have them for unlocking the doors with a " key bob " , or whatever it's called :>) . I have isolated the Circuit City installed Python burglar alarm out of the equation, the door locks should work manually with the operation of the switches on the doors , ( they used to ) :>)
Well, I have all of the Helm service manuals for this truck and have spent hours studying the door lock circuits. First of all the right door will unlock with the switch on it's door but that's all that works for the door locks , the right door will not lock with the right door switch. I figure there is either a switch problem in the right door or a bad , " motor " in that door, I'll get back to that after I get the left door operating.
Multiple problems are always fun :>)
In the manual the circuit picks up 12 volts at the I/P Fuse block, the fuse is good , then it goes from there to the Convenience Center , ( Orange wire all the way to the door lock switches according to the Helm service manual schematic ) . In the left door there is a factory splice which takes 12Volts to the passenger Door Switch in the " Crossbody Harness " still an orange wire .
The Orange wire is supposed to go on to the left door switch. Here is the problem . There is power at the right door switch, ( orange wire ) . There are 5 wires on the left door switch and none of them are orange and none of them have 12 volts on them .
My goal here is to get the 12 Volts to the left door switch. I'm writing here in case someone has run into this problem before , ( the wire changing color ) . I'm wracking my brain trying to come up with an approach to tracking this down short of unbundling " untaping " the wire bundles.
The only fuse in the circuit is in the I/P Fuse Block and it's ok. the circuit just goes in and out of the Convenience Center thru 2 connectors, one in and one out , no fuse
Any ideas on tracking this down would be greatly appreciated. I need to find out where the orange wire changes color :>) The Helm Schematic shows this 12 Volt Circuit wiring Orange all the way from the I/P Fuse Block , ( 12 Volt source , hot at all times ) to both Door Lock Switches on the Doors.
