2006, H-3 fan switch

[RangerRick]

Turned on the fan switch and nothing. Played with it and on the higher speed I heard a click coming from behind the glove box or kick panel under the A pillar. Dont know which.
It came on later after I hit a bump in the road, but I smelled a burnt wire smell and I shut off the fan. 10 minmutes later, I turned the fan back on it worked and no smell. I am in North Idaho-It's cold.
Where can I find the fan switch relay and any other thoughts appreciated.
Best Regards,RangerRick

Connector to blower resistor. Right side by pass feet. Take out glove box and go fixing. GM on line $100. 00 cheaper than dealer.
