F150 Gem Codes Help
My 98 f150 4.6 4wd has not been working. I took it to the dealer to have the GEM codes read and here were the results:
P1820- Transmission transfer case low to high shift relay coil circuit failure
P1828- Transmission transfer case high to low shift relay coil circuit failure
P1832- Transmission Transfer case (4WD) solenoid circuit failure
B1352- Ignition key in circuit fault
B1398- Left front power window relay circuit failure
B1434- Wiper speed relay coil circuit failure
Now, the only issues i am having is with the 4wd, nothing w/ the ignition, windows, or wipers. Does this look like i need a whole GEM or could these all be relays that need replaced? Thanks!
