How do you change the ignition control module in a 1988 Chevy Silverado 5.7L
Located left side of dash by powertrain control module (right lower of glove box)
It is beside of the battery just under the upper radiator hose.
A 1999 Ram does not have a transfer case control module.
It does not have a cable. It is all controled by the PCM. Power train control module / COMPUTER.
Located on the frame under the truck, close to the driver side.
it's located behind the headlight switch and push button 4wd control. the plastic piece just pops out to reveal the transfer case control module. good luck
It is located on the transfer case this is the motor that shifts your four wheel drive
The most common and cheapest fix has been in the pushbutton control on the dash. However it can go farther into a shift motor and/or a transfer case control module.
Should be located in the passenger side kick panel.
