Spent some time trying to fix a dead a/c unit recently. I purchased all the caps and desoldered, resoldered the new ones with the correct polarity. Dropped it in the dash and reconnected and nothing.
I then continuity checked all the fuses in the 3 fuse boxes and they're all fine.
I then buzzed through all the various connections/tracks on the underside of the climate control unit circuit board and no signs of any broken tracks. There had been some minor leakage from the old caps onto the board, however this doesn't appear to have damaged the integrity of the board connections.
I did notice that there is a capacitor on the smaller circuit board that is mounted in the digital display head unit for the climate control - has anyone ever had to replace this one.
I am in the process of obtaining an EV meter to confirm the capacitance of the new caps but wondered if anyone had come across this before after changing out the caps which seems to be the typical cause of climate control system failure.
I do have power to the board since the blower fan started up when I was checking the voltage on the upper right hand set of pins on the 28 pin connector.
