Ok, it's too cold, and getting worse, time to be less lazy.

Backstory, plugged in a 100W power inverter in, all was well, no hot wires. Then my blower motor pooped out. Wasn't the resistors because it didn't work on high. Lazy, I just unrolled the windows and quit using AC. Magically a week later, kicks to life, works for weeks.

Plug a 150w inverter in to charge my laptop, start the truck. Blower motor dead. This was in June. It's still dead.

However both times, all cigarette lights work with cell chargers.

About 2 weeks ago I start my truck. Lowbeams, inop. High works, low won't. Blubs ohm out, fuses good, swapped relays, not seeing anyhinng obvious.

Something makes me think all 3 must have a common something. Is there a shared ground point somewhere? Can't seem to find much on google. Or somehow I have 3 odd things break.

 

I think your dealing with separate issues, you might want to check the connector at the blower switch for melting or burning.
Otherwise you need to check powers and grounds at each component and see what's missing.

 

High and Low Beams share the same ground.
You need to see if you have power to the socket.
Red/Yellow and Red/Black are wires for the Low.

I’d start at the Lo Fuses for the head lights. Check them for power.
Then go from there. If you don’t have power to those fuses, don’t bother checking the socket. They don’t have power either.

 

Came in to posy this and look for my multi-meter, I just remembered that I just started to notice my AC light will flash, regardless if in I have it set either full hot/cold. If that has something to do with it. Just seems like 1 progressive problem getting worse. to me.

 

Have full power on anything I test either fuse or relay, swapped relays around, no change.

 

If you have power to the Lo Fuses, then the next step is to go to the socket.

 

The A/C light flashes when the A/C Amplifier does not detect the correct speed signal from the Compressor Lock Sensor when it engages the clutch.
The first step would be to see if the compressor clutch engages momentarily when the button is pressed.
If it doesn't you need to check for power at the compressor clutch when the button is pressed.

 

It all of a sudden stopped today, when I move the knobs on my HVAC (any of them) I can get a faint whine (even the ones not related to the blower) something goofy is up.

At the bottom, anyone know where EA EB would physically be located? Should mention it's a 2011 2TRFE

Edit: facepalm, location was on the next page.

 

Fuck it. I'm buying a new truck. as much fun as it is to play in -2 degree weather. I quit.
