Chad Fletcher, there should be two fuse box locations. One is under the dash on the driver's side. The other fuse box is under the hood, between the battery and the left fender. This fuse box contains many relays in addition to fuses. Be sure to replace the cover and ensure that it securely fastened to prevent dirt and moisture from getting into it. I attached a few images from the manual that might help you with your problem. Also, check this video, just in case. I hope this helps, good luck.
Dodge uses a bcm or fcm for most of there fuse and relay work there is only one fuse box most of the time and you wont necessarily find fuses for everything as may are lumped together however there is one fuse overlooked called the IOD. IOD stands for Ignition Off Draw and usually provides memory power to the BCM and security ECU as well as the radio, with it pulled the interior lights and power door locks won't operate.This fuse is a dealer installed item, IE the factory pulls it after testing so that the battery doesn't drain as fast while the vehicle is in transit to the dealer.Try replacing this fuse first .If this doesn't help a complete fuse panel replacement is a sure fix as these panels with the fcm (front control module) or bcm(body control module)can prove to be a rats nest of trouble with cascading problems. An occasional help is to remove the module on the end of the fuse panel usually next to the fender and clean the connectors looking for corrosion . This is usually a short term fix.R and R the fuse panel is your best and quickest fix. A lot of time can be wasted rewiring and cheating the panel. Sorry cant have a cheaper fix but Ive played with enough dodges to know that even though its an expensive fix in the long run its also the cheapest
There is only one fuse box on the 2006 Dodge Grand Caravan. Its under the hood on the driver's side. Its called.an integrated power module or ipm for short. Do not waste your time under the dash.
