power window issues 1990 1hzj77

[monst6]

New to me 1HZJ77 power windows are finicky.

Issues I have seen so far.

Passenger front window won't roll up from master or user switch until I turn off and on the car.

Rear driver side window wouldn't roll down from the master, worked from user input, then start working from the master.

Seen this a few times so far, I would assume its cracked welds in the master switch. Wanted to get a second opinion before ordering a new master switch.

Hi, I work in an hzj80 with the same problem. I changed the master switch but the problem continues. When it does not work, wait 1 minute and go back to work, maybe the engine or wire are wrong. Try to check the motor by connecting the connection directly. I think the main switch is overloaded. I have not had time to verify because I'm installing some fog lights.
But I hope the information will help you.

Regards

Hello,

Aside from the switch, you should also check the relay.

Hope this helps.
