Blower Motor Doesn't run

[VTRangeuh]

The motor gets power from a relay

Yup searched for that for half an hour yesterday before I realized the '95 schematics weren't the same.

Yes, very good job on finding the prior hackery.

It sounds like you know what you're looking at, and that you know what you're doing. You already know to use proper gauge wire for the repair; good!

New resistor blocks, and even a new pigtail connector for it, are available and relatively inexpensive (at least, the last time I looked). That connector on it is bad about being heat-damaged after years of use; if it looks melty or brown, may want to look at replacing it.

Great job; you've got things well under control.

P.S.- Where's my manners? Welcome to TRS!

Yes previous owner being my grandpa and his dad who was quite... Handy. Already had to replace the resistor block few years back and basically every connector needs cleaning or replacing... Sigh, I'll get to that some point.

And thank you and thank y'all for the assistance!

Spliced in some new wire turned it on and nothing. Realized I'd left the fuse out, reinstalled and still nothing. Realized I'd also left the motor unplugged, plugged that in and finally the motor worked. Here's some of the before pictures for anyone curious:

Bad wire with the cremated remains of the butt connector, and the melted spot on the wall

Just the connector end with the butt connector core in tact

Doesnt seem like the connection was bad, just exposed to the elements and eventually weathered away. I might try putting some electrical tape over it to extend the life, but for now I'm clocking out.

Two strikes, but then you knocked it outta the park!


Thank you for posting the pictures. They're classic examples of what air exposure, moisture, heat and time will do to 12 volt electrical connections.
