A/C heater knows not working anymore, changed the blower motor and resistor still nothing. Can anyone help?

All of that checked and good, still can't find the problem. There's power to the blower. Should I change the switches

check the switch with a volt meter.

Changed the switches, now the back works but the the front won't blow. The switch turns on though, any suggestions

now when you changed the switch/switches,did the front start working,or are you just changing switch today?and what switches did you change,blower switch? were there any signs of blower motor or resistor connectors melted>

No not burnt, changed the front and the rear comes on but no air in the front blowing. The blower and resistor I changed also. Fuses were good also, not sure what else it could be. Heated seats working also. Does the actuator have anything to do with that?

what actuator? is the blower not blowing/coming on period? and you are 150% sure fuse and blower motor relay are good? you have two fuses,one for each?

Didn't see 2 relays but will check again. The blower comes on but it don't blow out the vents in the front only the back
