This is a Repair & Return service for your Ford 4x4 GEM (Generic Electronic Module).
 
You will need to send us your original unit for repair—this listing is not for a replacement module.
 
The GEM module controls key vehicle functions such as 4x4 operation, wipers, power windows, interior lighting, and other body-related systems. Over time, these modules commonly fail due to internal component breakdown or moisture damage.

Battery drain or electrical shorts
Random chimes or warning lights
 
Our Service Includes:
Thorough inspection and testing of your GEM module

Moisture protection and preventative reinforcement
Final bench testing to ensure full functionality before return
