2002 rr 4.6 HSE US model - Pass side blower motor ran constant at full speed, checked relays and notice number 7 burned and slight melt and cracks under it on fuse box. replaced the relay but noting changed so I unluged the red wire from the pass side blower. drivers side blow ran the way it should so i left things that way. after reading other posts I was thinking the pass side blower may have shorted transistor(s). now the drivers side blower is not working at all and the new relay #7 is burned again. Question is should I focus on the fuse box or the transistors pass side transistor first. I did not yet check the fuses under the pass seat since the drivers side blower stopped working but will. Any direction for me?
