Hello Ford Mechanics at large,
I own a 97 Ford Ranger and about two weeks ago the cab blower fan (for
the Heat and A/C) started to intermittently fail. At that time when I
started the truck, I would turn on the A/C, and noticed that the fan
would "blast on" then turn off, then come back on, then off - next it
just stopped. There are no whistles or whines coming from the fan
(e.g. as if there was somthing stopping the fan blades).
1st thing checked: All fuses are good - no burnt one's found.
2nd thing checked: I purchased and replaced the inexpensive "fan
resistor" switch module from the local Ford dealer here. Turned on
truck, tested and it still fails - the fan resistor switch did not fix
this.
I know the AC is still working I can almost feel cold air coming out
the vents as I cruise down the road, there is just no "fan power" to
blow the air out.
Is there a next good step I can try to isolate this issue? I'm fairly
good with a electric DC Volt meter for a fuse box check or blower
motor fan "plug going into the blower fan motor" electrical test.
Any thoughts on a good next step check to fix this "no interior blower
fan" condition?
Best Regards,
Laynester
