Help - Wiring Seat Heat Problems
I just installed heated explorer seats in my truck and both seats work, but I am having problems with the heaters. I wired the two seats together in T and then brought the single wire to a relay. The relay has battery power and has switched power from the radio. When I first tested them the driver side switch lit up but the passenger had nothing. Now the drivers will flash quick and go out. It will only do it once until you cycle the key again. The relay is hooked up correctly, no fuses are blown. I don't know where to look next. Maybe a bad ground? I also checked for power at the passenger side switch and 2 of the 5 terminals have 12v I don't know which terminals are which, but there is power. The wire I used coming off each seat is 12gauge and where they join is 10gauge. Could the wire size cause a problem with too much resistance and not get enough power to the heaters. Also each heater has a separate constant hot from the battery. The wires that are T'd together are the switched power source. If you have any idea what I could have did wrong that would help me out a lot.
