My 91 has been super reliable for the longest time, but within only the past 2 years I've experienced a rash of electronic module failures. This includes....
1. Main relay
2. Turn signal cancel module (inside steering column)
3. Climate control unit
4. Fan control module (causes A/C to stop working)
It's ironic that a company like Tesla likes to suggest their cars are more reliable because it's "a computer on wheels" without an internal combustion engine, yet on a 25 year old car it's the electronics that are proving to be most trouble prone and not the engine!
I am wondering if it's worthwhile to proactively replace other electronic modules in my car? My understanding is that decades of constant vibration causes the solder joints on the boards in these units to eventually develop stress cracks and fail. Since I've experienced so many board failures in such a short time I fully expect there to be more failures of this type within the next few years.
What additional electronic modules have others seen fail the most frequently?
