hi guys,my mom's 2008 caliber keeps blowing the #23 fuse for the asd relay feed #3 as soon as you turn the key to the "run" position.the car crapped out on the road last week and my dad found the fuse was blown and replaced it.the car ran fine for about a week and then did it again.now it won't run at all.i saw on one forum for pt cruisers that this relay powers up the coils but i don't know if this is the case for the caliber.the car is a non turbo base model,any suggestions or info would be great.
which engine... 2008 Dodge Caliber: Available engines 4 Cylinders B 2.0L SFI DOHC (found in 84% of 2008 Dodge Caliber) 4 Cylinders C 1.8L SFI DOHC (found in 05% of 2008 Dodge Caliber) 4 Cylinders F 2.4L SFI Turbo DOHC 4 Cylinders K 2.4L SFI DOHC (found in 11% of 2008 Dodge Caliber)there are slight variations in the wiring...i can describe the circuits that are supplied if i can find the proper wiring diagramdo you have a digital volt meter.. and you will need access to the diagrams..i can help you with how it works..you will need access to eautorepair dot net or alldatadiy dot com.. if you don't have a factory service manual.. and a printer.. i will be back in a little while with some info on whats on fuse 23.. i happen have access to the 2007 caliber service manual .. thats probably close enough ..
if you are just blowing out fuse 23...there seem to be only 5 items hooked to that..4 ignition coils and one capacitor .. the wire could be pinched someplace.. or one of the coils with an internal short. even the capacitor shorted..disconnect all 4 coils.. leave the cap connected.. doe it blow the fuse.. you can ohm the individual coil primary windings.. or hook them back up one at a time..the wire color is Brown with a grey stripe.. got an digital volt and ohm meter?? there are 3 wires on it.. and the high voltage thru the spark plug.. i did not see a way to test the coilSTATIC VALUES:PRIMARY RESISTANCE 590 mW±10%PRIMARY INDUCTANCE 2.4 mH ±10%the middle wire is hooked to the PCM to pull to ground..the wire in cavity 3.. near the alignment pin is the power wire from fuse 23..
thanks wayne.i'll tell my dad and uncle to try those tests.i live almost an hour away from the car,so i'm the middle man-diagnosing over the phone.you probably know how much fun can be.lol
im having trouble with my wifes 07 dodge caliber same fuse as metioned in this post but my car is not blowing the fuse it is just not turning on I have narrowed it down to the fuse not getting power so to fix that in a bind I ran a fused power link to the fuse in the fuse box so it will run but if power is turned off to the fuse by the switch I out in the car will not start with the switch turned on it will run fine any help would be great

B_utterfield .. in the UNDERHOOD RELAY BLOCK you might want to replace the main relay..but first.. CHECK fuse 33 and fuse 18.. both of those in the big fuse box under the hood.. both should have power all the time..when you turn the key on.. if the fuses at 33 and 18 are good.. you will have power at fuses 23, 26 and 32... these are all controlled by the same main relay.. if you don't get power at fuses 23, 26 and 32... then change the main relay.. you can.. sometimes .. pry the electrical component out of the relay cover and plug it in directly.. please don't go probing around in the relay socket.. one of the wires is hooked to the PCM and you don't want to let the smoke out of that. fuse 23 sends positive to the ignition coils...fuse 26 sends positive to the fuel injectors..fuse 33 sends positive to two locations on the PCM..
thank you I will try that out and let you know what comes of it results soon
this may make me sound stupid but where is the relay block I know where the fuse box is are you talking under it where the wires come in to the box or is there a different box all together
pull the drivers side head light assembly.. i think its only a pair of bolts. carefully disconnect the wires to the headlight bulbs.. don't pull the bulbs unless they are blown out.. the side marker light you can pull the bulb socket out.. .. you might be able to see the relay box mounted to the outside of the frame rail.. sorry.. i should have looked for it.. i thought about it.. but i said. he will find it.. dodge did not hide important stuff like that.. well i guess they did..
its no problem I appreciate the help ill try that and is the relay going to be just a standard relay I can get at napa or something I will have to order from a oem store
this perhaps is the relay...i am not sure... i looked it up for a 2008 caliper.. the wiring diagrams i have are for a 2007.. could it use a different relay???? probably these or a direct replacement should be available at almost any parts store.. sorry it took so long to get back to you ..pull your relay out and match it by number.. or post the part number.. even google it..
