Truck (04 ext 4.2L) threw a P0483 code so I replaced the fan clutch, water pump, thermostat, and temp sensor. At 116K it needed it.
Before the repair, it wall of the sudden ran the temp you to 3/4, the SES light came on and bingo P0483
After repairs, Runs fine with A/C off, but w/ A/C on the temp climbs. I took it in to a local shop, and he checked the A/C and the head gasket and ran a diag and said the fan it not activating. He thinks the PCM needs to be Flashed, but his computer is on the fritz and he doesnt want to fry my PCM.
Thoughts ?
Should I hit up the dealer tomorrow and get the PCM flashed?
I'm $800 in to new parts and the diagnostics, not sure how much more troubleshooting the credit card can handle!!!
