Hello.
How did you check the relay’s? You need to check the Curcit betwen the IPD ( its under the Hood with bunch a fuses) and the blower motor connector. Un plug it and check for continuity(here we checking for open). Check for short. If here everything is good Check the climate control. CHeck for open between the Climate control and resistor/blower motor. You can find information how to do this on googlle.
Hope this helps.
