That's exactly my scenario, and the debate I'm having with myself at the moment too.RossDinan6 wrote: ↑Sun Apr 10, 2022 11:02 pmI may go ahead and replace the transistor since the evaporator box is out for a new expansion valve and evap clean. It would suck to have a failure right after assembling everything.
If the varnish was not present on the components, I would resolder a new Transistor in a heartbeat.
Is it though?
I can see that the power plugs are accessible under the dash.
But I can't really see a way to pull the plastic pins out of the clips to allow the module to be removed.
I had to push the pins from behind (inside the blower box) to allow them to be removed.
Yes, I have a replacement Transistor and heatsink ready to go.hornhospital wrote: ↑Sun Apr 10, 2022 11:41 pm If you are DIYing it, you might consider adding a heat sink like this. I believe the factory heat sink/mounting plate is borderline inadequate.
