ty adsm but do you know where i might start looking for the relays on the 4wd system

 

[adsm08]

There really aren't any "relays" in the system. Buttons send signals to a control module that sends signals to the motor. IIRC the relays that you are thinking of are part of the module.

where is this control module located and what does it look like

 

[adsm08]

Little black box below the radio and to the left.
