Trailer Tow Relay: Removal

WARNING: This page is about a different car, the 2005 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: To avoid personal injury or death, on vehicles equipped with airbags, disable the supplemental restraint system before attempting any steering wheel, steering column, airbag, occupant classification system, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the supplemental restraint system. Failure to take the proper precautions could result in accidental airbag deployment.
CAUTION: Be certain any removed trailer tow relay is replaced with the same relay size and type that was removed.
NOTE: The trailer tow relay bank contains four relays. The service procedures for each relay are the same.
  1. Disconnect and isolate the battery negative cable.
  2. Remove the trim from the right side quarter inner panel. (Refer to BODY/INTERIOR/QUARTER TRIM PANEL - REMOVAL) .
  3. Reach through the access hole in the quarter inner panel behind the right rear wheelhouse to locate and retrieve the trailer tow relay connector bank, which is wrapped within a foam rubber envelope and placed on the top of the right rear wheelhouse between the quarter inner and outer panels. See Fig 1.
