2002 chrysler voyager, panel lights won"t come on,

red light ? its the immobilisor ,can only suggest you have it taken to a dealer ,could be transponder fault or you have lost the chip out of the key .

Bulbs go out one at a time, if they all go out Most likely it's the switch Rotating the knob to the right the lights get dimmer, all the way and they are off All the way left turns the dome light on. Bad switch: no dash lights

there is another fuse panel inside.
I can't remember where it is, but you should check inside/behind the glove box.... or..... driver side under the dash.... or on either side of the dash where the door would hide it when closed.

I know the dodge/chrysler dash light fuse also powers the license plate light, so turn your lights on and see if you have a license plate light or not.
Hope you can locate the other box.

Does it play a cd? If so than the decoder for the dvd portion of the head unit may be bad. I would replace it if that's the case.

Have it properly diagnosed at a repair shop

Replace climate modual

have the mechanic look for a vaccum leak, and replace any old
vaccum lines, make sure the pvc valve is replaced.

my granddad has a voyager LX CRD, he has problems with getting the car into gear, as he says if you are lazy (cutting corners on the gearbox) it won't go into gear. we checked the gearbox oil and it was low and also it seemed that it was transmission fluid (for an automatic car) ALTHOUGH my granddads car was a manual. this is the one thing that chrysler don't come first for - Manual Cars
hope i helped you

Immobilizer? Its likely to be the 21 pin plug behind the heater control panel. Remove the long plastic strip under the control panel (prise of gently, held on by 2 clips) remove 2 screws behind this and 2 screws above on panel. The whole lot should easily come away. There will be 3 plugs, remove all three and try to start the car. If it starts your problem would be the earth. Hope it helps

I hate to say this to you but make sure the engine is not locked up. If you can turn the engine, either by pulling on the belt, or by putting a wrench on the crankshaft bolt, try another starter. If you can't turn it, try another engine. (sorry for the insensitive attempt at humor)
