Question We have a 2002 Dodge Grand Caravan where the headlights work, the break lights work but there is no dash lights, none of the gauges work and the turning signal doesnt work either. Any idea of what could be the problem or what to start replacing to get the instrument panel to work?
Answer Hi Justin,
All those failed functions are 'driven' by the body control module. That module has four fuses that operate it, in the power distribution box in the engine compartment. The most likely failed fuses are 19 or 20, both of which are 40 amp. The other fuses are 14 (which powers functions needed when the ignition switch is 'off' such as power door locks) and 24 (which power the hazard lights), So check that both fuses 19 and 20 are conducting and don't perhaps have a subtle crack in the internal wire. Fuse 19 is near the rear blower motor relay, and fuse 20 is near the front blower motor relay. Also check 14 and 24. 14 ia 15 amp near the name brand speaker relay socket, and 24 is 20 amp near the starter relay.
If you send a follow-up question clarify for me which 'dash lights' don't work, and mention any that do work.
