blower motor for air & heat does not work off of switch but, does work when directly hooked to batt with jumpers to plug on motor. brake lites do not work or i can get them to glow by pumping pedal. full pressure on pedad does not lite them. have gone thru three relays, blower switch, resistor & brake switch. nothing changes. can get relay to vibrate or hum by disconecting plug in at blower and reconnecting.

Just a thought! By any chance have you lost your ground/continuity? Check to ensure the blower motor is grounded, with a jumper and see if that may be your problem with blower.
