Tccm easy fix 02 envoy

[cobblershelli]

I went thru hell trying to find damned tccm on my 02 envoy.
UNHOOK NEG TERMINAL FIRST ON BATTERY
FYI: if you have an 02 or 03. Purchase a tccm from a used 04 or 05 and it's total plug n play

EASY FIX NOW

POP LITTLE Side PANEL ON DRIVERSIDE DASH with flat blade screwdriver. REMOVE PANEL

LOOK BACK INSIDE TO LEFT
REACH IN
UNCLIP TCCM FROM HOLDER
UNPLUG WIRES
REVERSE TO INSTALL NEW ONE.

USED ONE I INSTALLED DIDNT NEED REPROGRAMMED TO VEHICLE. Worked right away!
