Ok so my 87 has power windows, but for some reason both the drivers and the passenger windows go really slow or not even at all down or up do they need a new motor or is there a cheap and easy way to fix them? Also thanks for all your guys help i dont know what i would do with out you

First check if the windows are properly seated in the channels. Remove the door panel and grease the rails. Use a lithium based grease. Its thinner and lighter.

Upgrade to a 100 or 120 amp alternator. You can find them on 84-86 Camaros. The alternators will have V-belt pulleys. You can upgraded your current alternator up to 120 for only a few bucks if you do the work yourself. If you want extreme like me, I installed an 08 145 amp alternator!!

Your trucks an '87. most likely it's time to replace those old window motors.

On the cheap side, you could take them out and clean them with some electrical cleaner real good, sometimes they get gummed up.

Most likely, it's just time to replace them, $45 or so a piece.

I replaced both my motors on my 87. They are just as fast as the newer vehicles.

also check for bad grounds and lose connections, I was only getting 7 volts to motor, and with a jumper box they would roll up just fine, so I switched to manual, then half a year later I was tired of my faulty so I rewired it

I hear putting relays on them speeds them up

I put relays on my origional 84 motors and they were very fast. Cheeper than buying new motors, worst case your out a couple bucks.

Auto parts store: NAPA, Advance, Carquest, ect
The motors from Auto Zone are cheap, both in price and build quality.
