Hi all, looking for some advise of where to start troubleshooting. So for the past months, my car has been going through an engine and transmission rebuild. Now that it's back together, i'm starting to tackle all the little items since winter slows things down a bit.
Yesterday while adjusting my fan controller, i was playing with the heater control switches to make sure hot water was circulating in the heater core and i noticed i had no fan speed changes from low to high. I didnt yet bother with the basic testing of the switch, but i did notice that when the key was in the accessory position, i could hear the fan blowing. If i remember right, the fan is always blowing on low ? and i know that for the high position, there is a high speed relay under the hood to check.
So my question is besides the basics of 1) Fuse 2) high speed blower relay and 3) switch. Is there any other area i would need to check ?
Before the motor and trans came out, it was working just fine which has me wanting to believe it's something simple such as something unplugged (or maybe i'm just hoping it's that simple :-) )
Thanks in advance
