Major electrical problems in a 2009 Chrysler 300C
Answered by David Morley · 24 Mar 2025

I kind of agree with the workshop you used that the problem was a prime candidate to be caused by the TIPM unit. This is basically a fuse-box, relay-box and electrical control unit rolled into one and, when it fails, it can often cause the problems you’re seeing all happening at once. This unit performs a very similar role to the body computer in other makes and models and it’s used to allow various functions of the car to talk to other components and functions.

I understand that the new TIPM hasn’t fixed things, but faults with these units are not uncommon and it wouldn’t be the first time a brand new component has been faulty before it has even been fitted. A good check would be to try the TIPM from a car you know works properly and see if that fixes the issues. Certainly, the random and grouped nature of the faults points to the TIPM in a big way. If it really isn’t the TIPM at fault, I’d start looking for a bad earth somewhere on the car that is causing the mayhem.

But try this test first. Disconnect the battery and leave it overnight. Next morning, reconnect the battery and see if the problem has gone away. It’s worth a try even though the fix may not last indefinitely, but it’s simple and free.
