A/C fan will not run at all, fuses are good and compressor runs, what do I check on 2005 Jeep Wrangler

looks to me like the blower motor has failed or the fan switch has failed. Wiring diagram shows a blower motor relay but I can't find it? I have changed the 40 and 10 amp fuses even though they were not bad.

If no voltage at blower terminal, check/wiggle connectior at the blower motor resistor. Possible burned wire, if so replace connector and resistor.
