I bought mine last year with 180,000 and the suspension was shot.I did mine a couple of weeks ago on an 02 Envoy SLT. This forum made all the difference. I got the new seat heater in without any issues. I will say I threw out the three hog rings that I removed and replaced them with small zip ties. I just had to pre-curl them a little to get them under the dowel.
When I got everything back together it still didn't work. I read the replies and saw the forum about the broken circuit in the module. I took the module out, soldered the circuit, and then reinstalled everything. Works great now!
Replaced the 2 front wheel hub/bearings last week, the thermostat the week before, next is the motor mounts and then some suspension parts (sway bar ends?). The truck still looks great, but with 194,000 mi, it needs some attention.
The original passenger seat cushion heater failed last summer, (It still "works", but produces a hateful hot-spot mid-thigh) The driver's side--replaced in March 2011 with the Dorman heater--also failed completely again.The Dorman replacement unit is unfortunately made in Communist China
