I bought one of these on eBay last week:
And I got some more done on the Bronco this weekend. Got the door lock cylinder fixed and reinstalled in the door. It works great. I also looked into the power mirror swap some more. It looks like the guy was right, and that I have to pull the dash and install the whole harness. The harness starts inside the driver's door, goes through the door jamb, goes up behind the dash, runs all the way across the dash, right underneath the windshield all the way to the passenger side, and ends in the passenger side kick panel. That is all one huge piece. I also discovered that the power mirrors have different mounting holes than the manual ones that I currently have. So, not only is the wiring a PITA, but I would also have to drill new holes in the doors to mount them. Sigh...I was wondering if the conversion would really be worth it.
So, I decided to think about it later and focus on doing something else. So I started figuring out my power door lock issue. You press the buttons, and nothing happens. I got out my multimeter and start probing things. I discovered there was no voltage getting to either of the switches. I know the circuit breaker is good because the power lumbar seats and tailgate window are on the same breaker, and they work fine. So, wiring issue. I figured it was probably in the door harness (you know, the one I need to replace for the power mirror conversion?) so, I figured I should just bite the bullet, take apart the dash, and swap the harnesses. Remember that time I said I finally got the dashboard almost complete? Yeah, I guess not:
And, right after I got the old harness out, I tested it and found out it's fine, and the problem is somewhere else! Arghh, at least all the wiring will be in place and ready to go if/when I decide to do the power mirror conversion.
After studying the manual some more, I opened up the harness that runs along the floor, right underneath the driver's door sill plate. I found the power wire for the locks, and it apparently got pinched and was broken. I also found another wire that was broken. I'm not sure what that one is for, since everything else seems to work fine, but I think it was for one of the rear speakers. Anyway, I soldered the wires back together, and the power locks work! Whew!
Can you tell I had the dash apart again? I hope not lol
Hopefully it'll stay together for good this time. You can see my new dash pad in this pic. I still need to swap out the harness in the passenger door, which should be way easier than the driver's door. I'm also running new speaker wire to all the speakers; it's easier to fish the wire through that door jamb-corrugated-rubber-tube-grommet-thing that all the door wires go through while the harness is out. You can see the new wire poking out of the dash where the stereo goes.
I may get some new speakers for the doors really soon. Upgrading the stereo is on my to-do list, but it's basically at the bottom as far as priorites. However, I already have the door panel off and it would be nice to remove it only once. I'm also going to clean the door panels thoroughly before reinstalling. Did I mention that my future father-in-law smoked MANY cigars in this truck, and basically every panel has a nice brown coating? Gross. I think while I'm waiting for more money to come into my parts budget, I'll spend my time cleaning the interior. That's all for now.
