RELAY LOCATION

ApplicationLocation
"U" SeriesIn Underhood Electrical Center, At Right Front Of Engine Compartment

A/C COMPRESSOR CLUTCH RELAY LOCATION

WARNINGVehicles may be equipped with a PCM using an Electronically Erasable Programmable Read Only Memory (EEPROM). When replacing PCM, the new PCM must be programmed.

Note. To help save diagnostic time, ALWAYS check for blown fuses or fusible links before proceeding with any testing. If fuses are blown, locate and repair short circuit before replacing fuses. Ensure all related relay and wire harness connections are clean and tight. Repair as necessary.
