Atl-atl's K5 Blazer Four Wheel Camper "The Crawlin Cabin" documentation thread!

Maybe. Another issue is the rod that goes from the lock cylinder to the switch at the bottom of the column is broke or bound up.

Or, since you converted to a manual while still having an automatic column, the shift collar on the column moved which will keep the lock cylinder from rotating. Try rotating the collar counter clockwise to put it back into the “park” position.
Ok you were right about that. Tore the column apart and it had simoly rotated out of park. Got it back and the lock cylinder functions normally again. Since I have it all apart Im going to replace the lock core and ignition switch since they look really old and worn out. Still not sure thisnis going to fix the window issue though. Since the switch had power in “acc” but not in off I think the ignition switch was functioning correctly.
 
you can temp jumper the wires at the switch to roll up windows, if the window motor isn't the issue. It's a reverse polarity motor, so to need to switch both jumpers for up or down.

:doah:Forgot the 3 pedal conversion. My second thought awhile after post was double gasket oil filter.


Hoping to make it to Dino's too

Pro-tip to prevent that BS of the shift collar moving. Once you put the column back together put that collar in park and go under the hood and use some mechanics wire to the shifter arm to something on the firewall. It won’t do that again.

Now that I know what the issue was its easy to just rotate the collar if it happens again.

Now that Ive replaced the ignition switch my windows still dont work AND now it wont start, I think its not quite adjusted properly and I ran out of time to have the truck ready so I had to drive my “modern” rig on this trip and Ill come home to a problem that needs solving. So pissed :angry1:
 
Leaving it loose is a quasi anti-theft device. Just rotate it out of park when you leave. The switch can’t move even if somebody pops the cylinder out of it.

I say that knowing the manual trans alone is its own anti theft device. :haha:
 
Ok, windows still dont work. Whats weird is theres power at both windows. That points to one or both of the switches being bad, right? Weird though because I recently replaced both switches with high quality metal ones that appear to be in very good shape still. Of course my truck is a 78 so it has the much more expensive driver side switch that isnt in stock anywhere locally. At this point I guess I have to spend $75 on two new switches just to see if one is bad.
 
You can remove switch and use jumper wires to test wiring and motor. If it works switch is bad, if not you have a problem with wirinig or motor or regulator.
The motor is reverse polarity to up or down

Already tried this and the motors/windows operate normally. Seems odd that both switches would stop working at the exact same time though.
Also you can have power at switch, until a load is applied and it goes away. High resistance in the supplying circuit can cuase this.
Good to know. I think both sides were holding 12.3v whether the switches are pressed or not. If my memory serves me correctly. Ill try it one more time before installing the new switches.
 
Ok so Im thinking the issue is a bad ground. I tried the meter on it again while pressing the switches and voltage drops to zero when you press the switch up or down. I also tried something else to check the switches. On the passenger side the window switch is identical to the power door lock switch. So I tossed the "window" switch onto the "door lock" wiring and it worked! That tells me the switch works. Yay electrical gremlins!!! :doah:
 
Do you have a power probe?
No but I guess I need one hahaha. I think Im gonna start by tracing the grounds from the driver door where they pass through the loom by the door hinges. It cant be that hard to find, right?(famous last words!!) There are only a few wires related to the windows. I guess I could also stick a new ground onto the window switch but use its original power wire. That would be a really easy way to prove that its a bad ground.
 
give it a good ground with a jumper wire and test. you can jumper to power and test as well. Either can voltage go away when a load is applied.
