Still no blower motor updated pics
« on: November 04, 2013, 08:18:52 am »
So its not working at all. So far i have done
-Replaced Relay
-Replaced and tested blower motor
-Checked Fuse
-Made Sure had power going into the HAC Control
I have power going into the relay but none coming out on the other side to that red wire that plugs into the blower. I am stumped. Maybe i got a faulty relay??

 You can check your relay with a multimeter.

Do you measure power on the yellow wire at the blower resistor with the fan switch set to minimum?

It's difficult to know just how much you don't know until you know it.
In other words... if people learn by making mistakes, by now I should know just about everything!!!

Still cant get the dang thing to work.
-Replaced blower relay
-Replaced blower
-Replaced blower resistor
-Cleaned wires and connections added a extra ground
-Getting 12 Volts to the resistor and 12 volts on both sides of the relay. just cant get power going to the red wire that goes to the blower motor.
Thoughts?
Worse case can i run the blower motor on a toggle switch ?

i don't see one the one wire coming off the junction box goes all the way to the battery. Also if i had that fusible link where does it plug into at? the blower relay ?
