Keypad Issue

[scupp001]

The keypad on my 03 Exp EB is all operational except it will not allow me to lock the doors using 7/8 and 9/0 keys simutaniously. This issue all started when I had an aftermarket double din DVD player installed. Now the door ajar light comes on when I hit the rear defroster button and the courtesy dome light stays on for at least 20 minutes before eventually going off. Anyone experience this issue before?

I had similar electrical issues with my 02 xlt. The dome lights would stay on until the battery saver feature turned them off, the driver side puddle light didn't work, the keypad on the door would set off the alarm when I pressed it, the door ajar light would flash and beep at highway speeds, the radio would shut off as soon as I turned the key off, etc. Most recently all 4 windows stopped working.

A lot of electrical issues can be traced back to broken/damaged wire(s) in the boot between the body and the driver's door. I found 2 broken wires and repaired them. The thin black ground wire was broken and after repairing it all was back to normal. When the windows stopped working, I repaired the thick black ground wire and the windows now work like a champ.

Here is a great thread for checking for broken/damaged wires, thanks to synyster for this awesome write-up: http://www.explorerforum.com/forums//showthread.php?t=270081

Be sure to take your time when looking for broken/damaged wire(s). When you think you're done looking, look again, and again, and again. A bright flashlight can be very helpful.

Good luck!! :biggthump
