1999 Ford Windstar cargo, 3.8, 115K Both rear and cab overhead lights don't click on when the doors are opened The both have similer 3 postion switches (on the fixture) that appear fine (I took the rear one apart-seems to line up and contact and no corrosion) I can turn both on manually by moving the switch to the third position In the first and second position the lights stay off I don't see any door switches that poke out of the door or jam that may indicate a shut or open door, except on the cargo side (sliding) door, There is also a dash light that comes on if a door is open when the vehicle is on This dash light has occasionally been on when all the doors were closed Previous history and whether both dome lights stopped working right at the same time are unknown What would keep both cabin and cargo dome light from working in the "Door" position? There must be other switches somewhere...right? Any help is appreciated

I have a 92 delta 98 olds, and having problems with the fan motor coming on. I can set the heater controls and call for heat. All of the functions, defrost, and the different air direction valves seem to be working, because I can hear the "shutter" open and close, but the fan only comes on randomly. I have checked voltage at the fan motor when the system is calling for heat, and there is no voltage there. When the motor does come of course there is voltage there. I have checked under the hood for a possible loose connection, and so far have found none. I think I have traced the wires to go through the fire wall into the dash section. I have went to the local parts store and looked at the schematic, and it looks like there is a high speed relay, and just a regular relay in the circuit, before it goes to the controls. Can anyone help me with the location of these, or possibly another sensor that I'm missing? Like I said the fan motor comes on, but with no regular sequence. Sort of comes on when it wants to, letting me know that possibly there is a loose connection or maybe a temperature switch that is hung up or something. Thanks for any help you can give...
