*tipm issue solved*
Had exact same problem as poster. Exact same troubleshooting results as poster testing the electrical light beam connectors. Found electrical manual for 08 patriot online(it's the same as 07 compass) and tested all circuits sharing the same circuitry as the low beam lights from the TIPM, as well as the grounds. All checked out good. Problem had to be with the TIPM. I also had other circuits stop working since an earlier date such as the sunroof no longer operating, and the rear wiper intermittently. After researching it the problem is that during some condition (ie. rainy weather) some circuits experience overcurrent. The TIPM detects this and temporarily disables the circuit, then re-enables it when it's safe again. After so many occurrences the TIPM permanently disables the circuit (ie. there may be voltage but the TIPM will not allow current to flow.) hence why the correct voltage and ohm readings, but it's not working. This is because the circuit is switched 'on' or 'off' by the TIPM (like a transistor or relay.) Each TIPM is programmed to the VIN number of your vehicle from factory, with those feature options specific to your vehicle. Swapping with another TIPM from another vehicle may cause you to lose features specific to your vehicle. (Internet tidbit: Take this with a grain of salt but I read on a forum somewhere that a used TIPM may be re-programmed up to 4 times.) Either way swapping your TIPM is risky. However, if you get a brand new one such as the poster did (or try your luck with a scrapyard one that *may* be able to be reprogrammed up to 4 times?) there is a procedure by turning the key such as the poster did (look it up first before attempting) that will flash the new TIPM with your vehicles programming via (if I recall correctly) decoding your vehicles VIN to enable the features that you have. However, before doing this, I was able to *SOLVE* my TIPM problem by going to the dealership and having them do a full-diagnostic check (hooked it up to the $20,000 manufacturer computer) to read the errors and clear them. For $100 they did this and provided a printout of all the errors they found and reset for me. I would suggest trying this first. This fixed both my low beam light problem (which started as low beams and escalated into only passenger high beams working - yes, once your low beam goes out the other lights get more current and start to get disabled as well.) and my sunroof issue, and my rear wiper issue. Everything started working again!
I fully agree with the poster that this TIPM problem is complete bull**** and that the manufacturer should have been held responsible to issue a recall, yet this issue is so hard to prove because no one has any experience with this. So while it is difficult to recreate this and record results repetitively as such is required before a recall is issued, the proof is all over the internet forums that Jeep has ****ed everyone without any remorse. Merging all electrical components into one unit to control them yet providing no way to isolate or fix the circuits when something goes wrong is a big **** you to consumers and shady of the manufacturer. Shame on them.
Anyways I hope this helps anyone who comes across this post and is at a loss as to what to do.
