Is there a relay for the ac/heater blower and which one is it

The controls arent turning on the blower or ac. I hot wirered the blower motor and it works. hear the motor running but even hot wirered not blowing through vents. The fuse to blower is good under dash.Any ideas?
 
Year model would help. On early XJ's the heater relay is mounted on the air box above the passenger's feet. Only blowing through the defrost is a symptom of a vaccum leak.
 
ok found the problem. Turned out to be a bad connection at the black wire harness that plugs into the back of the control switches. Cleaned the connectors up and everything is working again.(ac,blower,aux fan)
I searched alot and everyone either suggested,fuses,relays,vacuum lines etc. So check out the harness with the purple w/yellow wire,if you have the same problem.
