  post locked   transsport windows dont work  

1993 pontiac transsport 3.8 ltr.
I own a 1993 pontiac transsport and have a question if anyone could help me please. my drivers side and passenger side windows stopped working. I checked the fuses in the glove box and all were good, I checked the circuit breaker below the glove box and that was good. I am running out of options, I tried a new switch for the drivers side with no luck, am I missing a fuse or can anyone tell me a location for the window fuse? I tried running the windows while opening the door to see if the wire may have broken!I also tried a new switch. email is personal info deleted

You could have broken wires or any number of other issues. The circuit needs to be troubleshooted by following a wiring diagram.

Probably a good place to start is by checking for power with the ignition on at the circuit breaker using a 12 volt test lamp or volt meter.

I am not any good at checking power or diagrams. I did switch out the circuit breakers. and tested all the fuses with a continuity tester by the glove box. I heard there might be a fuse under the hood, but I do not know where to look. is this possible and does the driver side switch if broken mean the passenger wont work either?
thank you for your help

Your going to have a hard time figuring this one out unless you understand how to use a volt meter and or test light to check different parts of the circuit in that diagram above.

Unfortunately that leaves you with either this option or paying a shop to do it for you.

lol. guess when it gets a little warmer I will check the wires going through the door to see if they are broken. guess there is no fuse under the hood from your responses. or pay 2 hours of $85 per hour to have mechanic look at it. the dome light does not dim when you press the switch. I did have to put a ignition module in last week. guess mainly I dont understand how to read the diagram. I always thought the windows had a fuse somewhere and a circuit breaker. I just cant find a fuse to check first.
thanks anyways.

You can see in the diagram that all it has is the circuity breaker.

2 hours to diagnose a power window problem? Do you know anyone with a volt meter that knows how to use it to check circuits?

yes. I will ask him if he can do it. its like 6 degrees out here in wisconsin, so I will probably have to find a heated garage or wait for warmer weather.. thank you for the help

one more question, if I dont find power going to the circuit breaker. where would I look from there. I will have my neighbor check it out. what powers the breaker?

Does the front blower fan motor work on all the low speed settings?

That eliminates the fusible link and the ignition switch. Power from the link goes to the ignition switch which goes to the power window circuit breaker when the ignition switch is in the run position. The circuit from the switch that feeds the power windows also feeds the blower motor low speed relay.

You still need to check for power in the CB cavity with the ignition on. Then work your way down the schematic until you find out where the open is.

I'm not sure where you got that quote from to diag a window issue but if it comes done to taking it to a shop, you may want to call around to some other places...

the circuit breaker is getting power! the door switch does not get power. I followed the pink power wire through the door and into the engine compartment and the pink wire does not get power to that point either, guess now I have to follow the pink wire through the harness back to the breaker to find out where the break is! correct? its snowing now so I give up......is it possible to just run a hot wire to the pink so it works with like a inline fuse or will that wreck something? I will check back tomorrow to see if you post. I need a break. lol and rest.

You've already narrowed it down to an area of breakage, so at this point the easier fix than rigging a wire is to open the loom up to the point it meets this circuit breaker and just repair the break. Then the next guy who runs into working on this van's electrical trouble in the future isn't confused by all these ghost wires that are no longer hooked up. You're on the right track here. Its snowing at my house too, just got back from the store before it gets too bad.

Right in the door jam is the most likely spot for the break.

thank you. I did check the driver door jam but not the passenger yet. I will follow the pink wire back and see what happens. probably next weekend. looks like the harness goes down by the bottom of radiator, starter area, so I have to jack it up and crawl under the van.... I did have a catalytic converter put on last week that was red hot on the inside and the repair shop hosed it off to cool it down, I will check to see that area also, thanks again, I will come back and post the results!

No, no, no. This will be at the driver's door. The wire runs from the fuse box to the driver's switch. Just find out where it loses power.

looks like hammer was right. I took it to a shop and he found a broken ground wire in the door jam! when my neighbor checked for power to the switch he was trying to use the ground that was broken during the test. anyways I think I learned a little more from all your help. thank you so much.. and the mechanic only charged me $80.. that's half of what the other mechanic wanted.
thank you again. :O)

Glad to hear you found it. You learned a little about testing electrical circuits too.

Question closed as solved.
