Hello jmak124
Your problem sounds like a magnetized relay; the field is weak and decays over time.
I just fought through this issue on a Jaguar and BMW, trying to explain the problem to a cheap skate mechanical illiterate in both cases was a major PIA….
Replace the relays and you should be golden.
Have a great day.
