I had a 1969 Ford F100 and it had no such problems. Any problem could be diagnosed in about five minutes. You didn't have to remove the dash to work on heater, change one of the dash lights or turn signal beeper. I drove that truck for 39 years with very little trouble. I drove it across the country three times and took it to the desert countless times.. Men would knock on my door and ask if I would sell it. I did sell the truck when we moved into a senior community but I wish I had it back.
