Your problem is with the steering wheel switch being to sensative not the relays as you said it yourself.
You can try and open up the contacts inside the wheel behind the airbag.
You only need a good set of tools .
Remove the 4 bolts ,2 on each side of the airbag once you pop off the plastic covers to acess them. They are located to the left and right of the wheel behind them.
that is it as the switches are right their as part of the float assembly holding the airbag.
I think it is 4 hex screws
