FORD has many related problems it REPORTS w/ the GENERIC ELECTRONIC MODULE (GEM) in the EXPLORER & the F250/350's. They have a factory recall on that part for those trucks.
I have a 97 f150 w/ the same problems & I'm reading about how others on this site w/ f150's have the same problem as well.
Do you think Ford has a Different type of GEM MODULE for the EXPLORERS & F2/350's or do you think FORD forgot about the 150's?
I called Ford's COUSTMER SERVICE SUPPORT LINE to inform them of my situation. They said they have not heard any complaints about F150 GEM's.
Do Your part if you have a 4x4 shift problem & call FORD at 1-800-392-3673

Ford recalls Explorers due to 4x4 lock ups & air bag problems
June 6, 2000
Ford Canada is recalling certain 1999-2000 Explorer because the generic electronic module (GEM) could experience a condition referred to as "lock-up."
This could cause a situation where the GEM controlled electronic functions (e.g., front windshield wipers, interior lights, 4x4 system, etc.) could not be turned ON or, in some cases if the function is ON, could not be turned OFF. An inoperative front windshield wiper system could adversely affect driver visibility.
18,576 sport utility vehicles equipped with 4.0L engines and All-time 4-Wheel Drive (A4WD) powertrains, sold in Canada between September, 1998 through September, 1999 are affected by this recall.
Dealers will install a resistor in the GEM circuit, which will prevent the electronic noise on the diagnostic link from affecting the GEM during vehicle operation. The manufacturer has reported that owner notification began April 15, 2000. Full information is available at Transport Canada's website <http://www.tc.gc.ca/roadsafety/Recal...sp?recno=8128&
Owners who do not receive the free remedy within a reasonable time should contact Ford at 1-800-392-3673.
