i think i've diagnosed some faulty joints in my instrument cluster ('88 m3)
my left turn indicator doesn't light up (exterior lights work)
right illumination bulb doesn't light up (tach and engine temp)
obc illumination dies when i turn the headlights on
i've checked the bulbs, all are fine. i've also consulted the wiring diagrams and it can't be a wiring problem or fuse issue
so that leads me to believe i have some cracked solder joints or something on the circuit board. has anyone repaired their clusters in a similar fashion?
i'm going to "borrow" a friends cluster to see if the lights do work. then i'll go down the road of either resoldering the board, or cannibalizing his cluster to keep my odometer reading (his will be turned into a j-stock car so he doesn't need that crap thats broken on mine.
i haven't taken a cluster apart, so is it even possible to swap tachs or circuit boards? how difficult is it to reflow cold joints?
