This repair took place quite some time ago, but is worth relaying: Think I mentioned this in another thread a long time ago. The hatchback door stopped working out of the blue inside the first 6 months I drove it off the lot. Whether I press the button on the remote to open the hatchback, or I use the button/lever on the hatchback itself, it would blow the fuse immediately. Went through about 5 fuses trying to troubleshoot it. I had just had an amp put in the rear of the car, next to the spare wheel, that was running a 10 inch sub, so I was hoping that wasn't causing the problem.
The rep. at Citrus Ford in Ontario told me REPEATEDLY (as if I didn't hear him the first time) that if the installation of the amp/sub was in any way involved in the failure, that I would be on the hook for all the repair costs and troubleshooting. I mildly questioned the relation of the hatchback wiring with stereo wiring and what kind of correlation they could have, but he was adamant. They took the car in, and had it for a couple hours. I was called back to come get the car. I was told there was no charge, the tech still had it in the bay, but I could go back there to talk to him (he was just finishing up). He told me it was a pinched wire that was done on the factory floor somehow. (If you have the hatchback all the way open, look at the canal at the top. There will be a plastic casing of wires that leads a couple things including the upper brake light. That casing had been pinched in the factory from misalignment and then ended up pinching the wire that pops the hatchback.) From all he told me he had to do to find the problem, he struck me as incredibly OCD about wiring. That is exactly what I want from a technician or a mechanic. People skills, not so much, but being that OCD about how things are laid out so they work right, YES. The Rep. didn't seem too thrilled that it was a Ford issue and not something that I, or 3rd party did, but that was OK with me.
