I am working on my girlfriends 2003 Explorer XLT. We replaced the transmission and on the test drive after the re-install the 4X4 High light in the dash flashes about 5-10 times every couple of minutes. The buttons on the dash (4X4 auto & high) don't do anything when pressed and the 4X4 low button just flashes 10 times or so when you press it. So, no 4 wheel drive. We did disconnect the battery cable during the process and I am wondering if that blew the module behind the glove box? I searched the forums and it seems that it may be the cause. Can anyone verify this, or have any other ideas? Thanks for your time.
