i just added power windows to my '80 model. i got used regulators but they tested good on the bench. now that i have them installed the passenger side will roll down, well it did once, but it wont roll up. i have put a new switch in and it still wont. it still trys to roll down because i can hear the motor clicking when i hit down on the switch. i tested for 12 volts when i hit the "up" side and power is getting out of the switch and to the wire but nothing happens with the motor. i can only assume that it is getting power to the motor but i cant test it because with the window down i cant reach down there to check it. is there something i am missing? any help is greatly appreciated.
