A few weeks ago, my airbag light came on. When I got it checked at the garage it came up as the drivers seat airbag, with the code saying the resistance was too high or something of the sort. The mechanic unplugged and replugged it back. After clearing the codes it went away untill the next drive about 10 mins in. I went recently and asked to see if he could try it with contact cleaner but to no avail. What else should I check/ do that can solve this?
