Window problems

[notrailerqueens]

ok so on the new 86 short box i just bought im having some window issues.

the truck has electric windows. the motor and the wiring to the switch in the drivers side door was bad so i bought a new motor and wiring jumper this weekend and installed it. (btw puttin that new motor in if you havent ever done it before is a PITA!) but never the less i took the truck to lowes today and the window rolled down fine but when i went to roll it back up i got magic smoke and the fuse blew.
so when i got it home i took the door panel back off and low and behold you cant get to the motor now cuz the glass is in the way. there-for i cant run a hot straight to the motor to see if thats the problem. now i put the multi meter on the switch and the switch is fine. if you flip the switch to roll the window down it works fine but when you flip the switch up to roll the window up it instantly blows the fuse.
ive looked at the wires and cant find one thats pinched so im at a loss. also because the mounting hardware for the motor is on the door skin side of the regulator i cant just drill a hole to take it off. plus to take the motor off you have to pin the regulator gear and i cant do that while its in the door.
so im seeking any kind of advise or possible solution i can get. thanks in advance. you guys have never steered me wrong in the past.

I don't know how to get the window back up, but I am sure someone posted a method to do it previously.
Just curious, what kind of harness did you install? The replaced the short two prong harness which attaches to the motor, and the harness at the switch, but they were not easy to find. The harness connector behind the switch has wires which "stab" into the side of the connector at a right angle, so they tend to wear/weaken over time. My guess would be that one or more of those wires broke loose and is/are shorting out when you activate the switch. I would disconnect the battery, then pull the switch out from the door panel. If this is the harness you replaced, it is possible that the wires may be crossed. I am attaching a pic of the harness connector I am talking about.

yah thats the one i replaced. i crawled all over it too to make sure none of the wires were pulled broken or pinched.
im just really at a loss here

So, did you pull the switch out after the smoke incident to see if the wires at the connector are still OK? If the connector is still OK and it is installed correctly, then it is theoretically possible that you have an internal short in the switch itself, but that is unlikely. Usually, a switch breaks internally but does not cause a short. If you can get the window up, that connector at the motor may have a problem.

[notrailerqueens]

yes i have pulled the switch out and its fine. i thought maybe that i had a pinched wire but the harness is all free and clear. ive tried to get the window up but so far with no avail

Do you have the old connector/harness? Can you check the color of the wires on the old harness to verify that the wires of the new connector match up correctly?

I found the trucks with electric locks maual windows the plug is the same the wires are in different spots tho
my 88 a wire broke inside that rubber tube to the door(easier access with the door open lol)
disconnect the battery and ohms meter the wires to see if there is a dead short

the wires in the boots break from the constant flexing opening and closing the door. It is a real pain to fix them on the vehicle also
can you get to the plug on the motor?
if you had an old motor plug with a length of wires on it you could plug it to the motor and put power and ground to the motor and bypass all the door wiring.

welp i dont have an old motor plug and because of the current location of the glass i cant get to the motor. i will have to check inside that boot to make sure everything in there is copesetic.

i do have the old harness and i pulled out the new one i just installed to look at it and they are identical in how the wires are run and how they plug into the switch.

Something else you can do is apply power and ground to the power motor wires at the window switch plug, with the switch removed, to roll the window up. Should be the heavy gauge dark blue and brown wires. apply 12v to one and ground the other, if it doesn't roll up, reverse the 12v and ground

[notrailerqueens]

im gonna try that soon as i get home. my buddy told me on his (hes had 3 of these trucks ironically hes had this happen to him on 2 of em) that the only way he could find to get it out is to scrape the tape off that holds the glass into the channel remove the glass and then use a reciprocating saw to cut the regulator out and then replace it.
im really hoping i dont have to do this.

[motornut]

do all that to get the window out?
4 bolts on the regulater push it in and it will drop the glass down
slide out of the track and then lift out of the door

well i didnt realize there was a way to get the chanel off the regulator with the window all the way down but if so that would be awesome cuz even my lil girl arms are a tough fit in the the "access" panells in the door. but even still i have to find a way to bust that regulator loose to get it outta the door.

[motornut]

Four bolts around where the manual crank would be
Loosens up the whole thing
One part of the track is welded to the door this is where the wheel will slide out
Wiggle and turn window i think it was downin the front worked,and up and put out threw the window opening

If you still can't get the window up and cant get to the motor pull the vent window and then you can slide the main window off the track. From there you can attack the motor just make sure to lube everything when you put it back together.

[notrailerqueens]

ill try that. the regulator wasnt in the best shape (wheels were kinda wobbely) but i figured itd be alright for a bit i did grease the ever loving life outta it when i put it back in but to no avail. *sigh* im gonna try pullin out that vent window assmbly and see if i can get the glass out that way so that i can get to that motor and free the assmbly up to pull it out.

[maynardtruckin]

What kind of grease did you use?

[notrailerqueens]

some red bearing grease.

[maynardtruckin]

oo big no no. use some white lithium grease. The bearing grease gets thicker as it gets colder as ware the lithium will not change. Sounds like the grease got thick and the motor was working to hard and fried. I would clean all the track real good and re lube everything real well you can never have to much and don't be afraid to check them every so often and add more grease as needed. grease is cheaper than electric motors!

[maynardtruckin]

As long as the wheels move free and are not falling off you are ok. If they are tight or falling off then you have problems. Not sure if they offer them but for some of the early regulators you can get replacement wheels that rivet on after you drill the old ones out.

[notrailerqueens]

welp win some loose some. the wheels werent falling off but their loose. crazy thing is that it rolls down fine. and the passanger side got lubed the same way and it works fine.

but it does not get used as much. for every time something goes bad on a passengers side door you have had to replace stuff on the drivers door 4 or 5 times in most cases.

[notrailerqueens]

touche' sir. welp looks like ill be tryin to pull it all apart here in the next couple days. bothers me cuz this truck lives outside and i HATE leavin it out with the window down
