let me double check one moment
when the relay is unplugged the fans dont run
Ok, now I want you to install the relay and remove fuse #27 (40 Amp) from the Intelligent Power Module. That's chrylser's version of a fuse box... it has fuses and relays in it. See if the fan stays off doing that.
pulling the fuse shuts them off
I unplugged the top connector they look the same, and the fans dont come on. if its the pcm sounds expensive
My bad i forgot to put the fuse in i have disconnected both the plugs from the pcm and the fans still run when the ground is attached to the battery
let me check
i have a small one from radio shack but should do you will have to tell me what settings to use etc
yes it reads 0
ok can i use the battery ground as a ground point if so 29.8
replace the wire seems simplest your thoughts
ok i will work on this and will let you know how it goes. both of the pcm connectors are solid gray so i will look for the brown solid wire what size wire should i use to splice i will have to get supplies for this so it will take a few to get back to you thanks for your help A+
do you have a diagram of the pin 73 wire there are a couple that look brown violet on the top connector to the pcm
Got it it may be tomorrow before i get to this when i can get into the garage with heat i willl pick up supplies today thanks again will rate you when finished
i cut these two wires and touched them together prior to finalizing the splice and the fans came on while they were touching with the switch off and the engine cold
yes they were could the issue be in the pcm block
yes on the old section of wire is out of the circuit pcm block ok i have to get the meter be a few minutes
zero reading on both then i plugged in the pcm and got a reading of 1.9 on the wire coming off of it, im in MN and it was so damn cold yesterday i cant say whether the pcm was plugged or unplugged but i was pretty sure i unplugged them
yes give me an idea of where it is, my fiancee is getting rid of the van in 3 to four months so we can do without ac if thats it,
ok unplugged ac sensor connected the fan relay wire to the pcm block and the fans started running, bout ready to put a manual switch in the fan relay line. off when its parked on when its driven rudimentary but this van is cursed
In my manual it doesn't say the computer needs to be programmed if replaced.Here are some cheap used computers (I've dealt with McCarty before, they have good parts.)McCarty Auto Parts USA-GA(Hazlehurst)(NNN) NNN-NNNN/(NNN) NNN-NNNN$50.00Grassy Auto Parts USA-KY(West-Liberty) 1-800-354-7402 $45.00
They will ask if you have flex fuel and you do because of the vin 3 that you told me in the beginning.
ok im with you i think the computer is the problem
Well, those used ones are cheap enough I think!
Did you check for voltage on the pressure sensor wire I mentioned above?
I hope you don't have any problems with the new vehicle. But if you do, feel free to look me up.
