How do I test therelays on my 1997 Grand Caravan? It seems that there is insufficent power to the motor (from the battery). There are relays under the dash and under the hood clicking when I turn the key to start it. Also the interior lights diman unusual amount.

 

Yeah I'm not sure I'm not really that knowledgeable about that kind of stuff, but I've always hears that if lights are dimming when applying brakes or window motors it's an early sign of alternator going out.?But like I said I don't know a whole lot about it.

 

I than would have battery checked out. If you look at the relays you can see that some are the same and switching them around can reveal if they are working. The A/C relay is one that is the same as others. Of course if you have a relay in question thats not working than something is not working also. I've seenmany times where a relay stoped working and it only need cleaning.
