Ive put the heated seat wiring in but only one side is working when i probe the wiring on the switch the test lamp is very dim it has a ignition feed but then when i use the ignition feed to power some of the switched wires my test lamp goes bright on the 4 pin connector to the seat ive checked the earth so im stuck

Now i used some wire to bridge some connections i gave ignition feed to the yellow wire which is the drivers side seat that is no longer dim and i bridged the passenger side wire to the drivers side wire when i use the passenger switch i have all 3 power feeds which i need to my seat now im thinking the switch is faulty as it is not transfering a strong current to the drivers side wire but the passenger side switch is giving good current is it my switch
