But problem only after a few months of working fine. And once code are erased its fine for a few weeks and then eventually comes back on. I doubked checked the wire and they are correcte. Inrermitent defectif Mr20 relay?
It's under the hood the relay?  Check for corrosion on the pins possibly. MR20 should be small enough to fit in a 1inch heatshrink. Could be worth it to protect it from the oustide world.
