On your battery junction box there is a 40amp fuse that goes directly to the relay. That may be bad, so check that. There is another under the dash that is fuse 24. If ist still isn't getting power see if the switch onthe heater control is putting power out or not. Alot of times they melt due to heat from having the blower on all the time. So you wil need to see if it is getting power into the switch and out.
