Blowers have once again fried their speed controls, could be that one had been gone for a while due to weakass pressure of late.
So time to take them out again, well actually I never did take out the passenger side unit as it seemed to work ok once I reflowed the fuseboxes.
Of course all this tinkering was in the past, maybe 10 years ago.This time I will be removing both blowers and in order to do the passenger blower I have to take out the airbag. I more than likely will leave it out too.
Anyway, last time I repaired the speed control circuitry I replaced all the components, caps, resistors and the big transistor.
Here’s the question …is it enough to just change the darlington transistor or do I do the whole shebang again?
I have 2 spare blowers but only the passenger side spare responds to the speed switch, drivers side spare just blows high or nothing. Even though the passenger side spare is OK at the moment I’m thinking of putting new transistors in both spares.
One more thing - with the drivers side blower out, would I have access to the upper blend door motor and or mechanism? (the upper blend door is stuck in the cooling position, lower blend door working properly)
