89 xj 4.0 AW 4 been running great for 6 months after replacing all that i figured i should have to on a new / used motor................ oil pump, rear main seal, timing chain and sprockets all new Felpro gaskets etc ... Anyway like i said it has been running like a top for 6 months and suddenly quit while i was driving it . I tested the CPS and wasn't getting the volt reading that i thought i should be getting so i replaced it and still no start ! has spark although seems weak and has fuel at the fuel rail at around 40 PSI . Anyway long story kinda short i thought i would check the timing today and all be damned it is out almost exactly 180 out !!! Do you guys have any ideas on how that might happen ? Thanks in advance for the help !!

Had an idea today... Can the rear window defrost circuit be used to power aftermarket heated seats? I know it runs on a timer like many OEM heated seats are. Thoughts?

I wonder if the heated seats use a circuit breaker.
I'd be willing to try a 30 amp circuit breaker in heated seats in place of the 25 amp fuse. Especially if it were on your Jeep and not mine!! LOL.

Since you two drive old junk I figured I'd look at my '95 FSM. Nada. So I hit my '97 ZJ and '99 FSMs and found some goodies. I'm too lazy to post pictures right now so here's the word version.
There IS a breaker, each seat gets 20A. Like everything else on these things the wiring is laughably small. The seats have built-in thermistors and are driven by control modules that ride the temp appropriately. At least on 1997+ Chrysler stuff.

25 amp circuit. 2 seats requiring 20 amps each. 40 amps. You would PROBABLY be okay with a 30 amp circuit breaker in place of the 25 amp fuse for the defogger.
I'm going to bed now. I get up at 4 am.

Big fat wire, separate breakers or fuses. The important bit is that the seats are driven by an active controller, not by a timer.
If you want to use your defog switch get a relay in there to drive the seats directly from the battery, and don't come QQing if your *** gets burnt lol
