I drfinitely need to get new glasses. If your now blowing both fuse D in the Power Distribution Center and fuse 20 in the interior fuse box it may be one of two things. Try checking the part numbers on both high and low speed relays and using a different one for an accessory you don't need at this time or get two new relays. Sometimes they mount spares in the PDC. Do a good visual to check the wiring out of the relays under this engine fuse box, between it and the fan. This is the only way your going to isolate whether there is a problem in a relay or one of the fan motors. Either one would take both fuses out if there is too much draw or a short in either speed fan wire. Let me know if you find it. Thanks and good luck. I think it's the high speed circuit in the fan.
