No high speed on fan blower

70 with factory air. I have a low, and a medium speed but no high speed with the heater on. I have changed the high speed relay but that didn't help. I get a feed on the single orange wire when I put the switch in high but the blower stops. The AC compresser is off the car right now. Any ideas what to look for? Thanks.

I'll have to check the wire feeds. I have put 2 diffent relays on thinking maybe the first one I put on was bad, but the second new one didn't help either. Maybe the in line fuse on the big orange line is burnt out. Thanks for the info.
