[QUOTE="TRevs, post: 440749, member: 20654"] Update: I've solved the short, sort of. I traced the green wires that both use the lug at the back of the #12 fuse; the '95 4.0 L wiring diagram looks a bit different than the one above, but they start the same out the back of the fuse. The short is definitely on the A/C side of the circuit, probably Z1 after leaving the connector for the A/C blower. My Jeep apparently did not have A/C from the factory ("Air Conditioning Bypass" is printed on the build sheet), but somewhere downstream is the short. Visually I don't see anything that looks like prior-owner hackery or cut looms, but rather than trace the end of a circuit I don't use, I cut the A/C C1 dkGrn wire a few inches behind the fuse, and the short in the heater blower circuit disappeared. I may eventually put A/C in, so I'd presumably have to chase down the short completely at that time, but hopefully I can at least get heat going since winter has arrived. (And hopefully I haven't damaged anything else in the process of disassembly.) [ATTACH type="full"]122391[/ATTACH] [/QUOTE]
