Not sure what small 2 prong plug is opposite side of blower switch is for ? It connects to another plug with a green and lt brown wires that go up & into the firewall. Replaced vacum lines and pretty sure I have a bad blower switch.Any input as always is appreciated
Not sure, but I would put a meter on the prongs and flip the switches until I get a reading. at least you will know what settings make the connection. If you get nothing across Id say the switch is bad.
A picture of the plug end of the wires; 2 light brown & a green wire , will check for power tomorrow.
