First time poster, long time reader, corny but what the heck.......
Have a problem with this fuse blowing on an 06 charger (mid 2005 build) 5.7L. I know its against forum policy to post schematics from the manual, but could anyone tell me what items are on the circuit that goes to fuse 17 in the rear distro box.
Reason i ask, the owners manual shows blanks for the fuse location, my overhead lights do not work, the trunk release button does not work, the green arrows for direction do not light on dash, and the climate control unit does not light.
I took the vehicle to the dealer and they wanted to sell me a new AC head unit for $367.00
Not asking for schematics, just what items do i need to pull to look for the dead short?
rear is not power distribution its the integrated power module
fuse 17 in the rear is a 30 amp.
Fuses run more than one thing. some of the things fed by this fuse are, wipers, abs module , but it runs a few other things too.
to find a dead short you need to remove the fuse and install a test light. This will light up if there is a short. pull the schematic and start unplugging things til the light goes out. I would start with the a/c unit the dealer recommended. it probably threw codes in the front end control module for something which is why they recommended it.
The factory service manual doesn't show a fuse in that position but a different wiring doc I have says it's a 20amp and is for "Cluster." Interior lights and trunk release are some of the items that this diagram shows are in "Cluster" that could be powered by this fuse.
Have you done any mods recently that could be causing this?
Haven't done any mods other than exhaust and CAI. Fuse 17 blows immediately with the car off and doors closed, i will have to track it down by unplugging everything on that circuit and plugging in stuff till the pop!
Well, I pulled everything on the circuit from fuse 17, plugged em back in 1 at a time, and it never blew again? Freaking Magic! So no firm answer as to why it blew, but fuse 17 seems to feed the cluster and there are 3 connectors off of that, so was hoping to narrow it down by plugging them in 1 at a time, but to no avail.
Now however i have a check engine light and codes 1403 and 1411, which i searched and found in another thread, off to try that fix......
Codes U1403 and U1411 are "Implausible fuel level signal" and "Implausible fuel volume signal" codes (I assume the codes start with "U" and not a different letter). If so, both of these could have been caused by removing power to the cluster.
As much as I hate to suggest this (don't let wickedchargerrt hear this) you might want to disconnect the battery for a few minutes to let all the modules discharge, then reconnect so they all synch back up together. If you still get the codes it's much more likely that the problem really exists.
u codes are communication codes. when you had the fuse plugged in and cluster unplugged you caused communication errors with all the other modules who couldnt find the evic (cluster module) while testing because it was unplugged. And thats why the fuel gauge code too.
