I searched around the forums already and alas haven't found anything definitive or that solves for me.. so figured I'd ask.

Trip computer resets back to zero every time i power turn off the engine. I have a brand new battery and the radio manages to keep its memory, so why not the trip computer? Odometer works fine. I'd honestly like to use the trip computer for measuring out my mpgs and trip distances between fills.

 

Any blown fuses?

 

alas... no. fuses blown. all of that seems to be working..

is there a wiring diagram that shows where the trip computer pulls from the battery so maybe I can try to work my way back to see if there's a corroded line or something?

 

What year is your van?

 

its a '99, b1500. the 5.2L V8

 

This link might help you with the wiring diagram:http://www.bbbind.com/free-tsb

 

Replace fuse 12 in the junction block. 15a fuse. That is what supplies the cluster power when the ignition is off, for memory. If that doesn't solve it, likely the cluster itself has an issue.

 

Thanks! Let me give that a try when I get the van back. Currently at the shop to get the heater core, thermostat, and heater control valve replaced.
