2002 ASD relay clicking -- need advice
I have a 2002 T&C 3.8L V6 w/ around 90K miles. Two weeks ago I pulled it into the garage and turned it off. I heard a noise coming from my dash of what sounded like was my CD player were trying to eject a cd. So I turned it back on and pressed eject, nothing came out. When I turned it off the second time not only did I hear a “whirling” sound coming from the dash, but there was also a rapid clicking from the fuse box up by the battery. I pulled the cover off the box and determined the clicking sound was coming from an ASD relay. So, I went and purchased a new one. After a simple replace, I again got the whirling and clicking of ASD relay as soon as I turned the ignition switch. Well, replacing a fuse is about as much as I can do in the automotive field. That is when I came inside and started my internet search. It appears I am not the only sad sack who has experienced this problem. Two days later I tried to start it and it was completely dead. Took the battery to auto zone who tested it (tested fine but low charge) and charged it.
A few days ago I called my local Dodge/Chrysler dealer and told them of my problem, that I have a good battery, and that I have seen a lot of posts where "experts" are suggesting a PCM replacement. I then told him where I read a lot of posts where people spend big $$ for a new PCM and they continue to have the same problems. The mechanic at the dealership told me it was likely not the PCM since the ASD relay is actually getting powered.
So today I go out with a freshly charged battery and try to get it started so I can take it to the dealership. Dead! Towed to dealership. The dealership calls and tells me it needs a new PCM ($730 + a $285 labor + taxes = well over $1000.00). I ask if he is sure that is the problem. He proceeds to tell me that they will not know if there are other problems until they fix the PCM and run the codes to see what else pops up bad. Does anyone else find this unacceptable. But I am out of my league and I don’t even know the terminology where I can speak with any sort of authority or know how. I hate cars, I hate dealerships and I hate service departments. I have an in-town mechanic I take my vehicles to do simple repair work but thought this issue required expertise of my vehicle manufacturer.
I am at wits end. Please help.

Please note that I found the best answer to my problem from a 2007 discussion thread at https://dodgeforum.com/forum/dodge-r...asd-relay.html It appears to be between user alloro and ejimcruz. I'm just not sure what the final answer was?? Was it the PCM in the end?
alloro states: You have a short in the wiring to ground on the secondary side of the relay (non-battery +12v side).
One, it's the PCM which is a 300 or so dollar gamble and I'm inclined to think it is not the PCM since the ASD relay is actually getting powered.
Two, one of the + outputs from the PCM (such as the fuel pump relay output) is where the short lies. My 30 years of shade-tree mechanics coupled with my 20 years as an electrician is telling me it is a short to ground. The ASD relay powers up the PCM, which in turn supplies power to other circuits thus engaging the short and power loss cycle I described in my first post.

RE: No Start, constant buzzing, ASD Relay
Maybe the short is in the relay/power distribution box itself. You might have to unbolt it and flip it over to inspect for corroded or melted connections.

PCM/ECM Shorted and Interior Light convertion panel relay defective.
You were right Alloro.. Thanks!
