I own a '97 Expedition with 119,00 miles. The "door ajar" message will not clear so I have disconnected my battery, this happened today. My radio turns on when it is “off”. Recently I have been having problems with my brakes. When the pedal is depressed it feels like the ABS is engaging. I have replaced the ABS driveline sensor, Master cylinder and the front driver side brake caliper. A few weeks’ back the problem occurred and I had a mechanic replace a pressure relief valve on the master cylinder that corrected the problem temporarily. The valve is not leaking currently and I am having the same brake problems again. I believe that all this may be related to an electrical issue.
Today I drilled a few holes in the bottom of my fuse box under the dash. No water came out. I am currently removing the fuses and will clean with electrical contact cleaner to see if that helps. If anyone has further ideas please let me know.
I also read about replacing the transmission range sensor. Where is it located? I will attempt to replace tomorrow. Thank you for all the help and information.
