My HVAC blower will not blow. I checked the fuse and it's good. It could be a relay, but I have no idea where to find that. What do you reccomend?

Start by applying power to the blower motor direct from the battery and see if it turns on-

I LOOKED UP THE DIAGRAMS---THERE ARE 5 MODELS FOR A WRANGLER IN '93

I USED "SE" FOR LACK OF CORRECT INFO

THERE WERE 2 DIAGRAMS, ONE WAS HVAC, THE OTHER WAS HEATER CIRCUIT

BOTH SEEM TO HAVE THE SAME RELAY INFO (LOCATION)

THIS IS EXACTLY WHAT IT SAYS (LEFT SIDE OF DIAGRAM, 1/3 WAY DOWN):

BLOWER MOTOR RELAY (ON HVAC) (IN WIRE HARNESS CONNECTOR, NEAR RIGHT END OF HEATER-A/C HOUSING)

KEEP US INFORMED ON PROGRESS

THE MEDIC

THIS IS THE "HVAC DIAGRAM" FOR A "WRANGLER SE"---THE ONE I DID NOT GET WAS "HEATER CIRCUIT"
