Door control module trouble. (Power locks)

[DRIFTINGmy85]

How many times can you guys lock and unlock your Supra using the power locks switch before it starts to make a grizzly noise out of the module and the locks freeze up and stop for a short period of time?
Does your Supra even do this?

I have an aftermarket alarm that has spliced into two wires off the Door Control Module connector. Maybe too much current is being pulled through and as a result the module gets too hot and a bad connection inside is created until it cools? That's what I'm thinking anyway. I just took the module out of my 85 which I never noticed a problem like this one and after about 5 on's and off's of the power lock switch the module did the same thing.

Thanks in advance!

What kind of usage? 5 back to back, or 2 days 3 times a day?

[DRIFTINGmy85]

Within like 5-10 second back to back.
The aftermarket alarm sets itself after a few minutes so I have to keep unlocking it. When I happen to unlock, lock, unlock, lock within a minute or two the door module I just took out would stick in the locked position for x amount of time. I instantly thought wiring problem the first time the locks plain froze and I had to enter through the hatch.
Since then it's done it twice where I had to wait to unlock the car to get in or out. The noise happens frequently.

I'll have to see how this swapped module acts. If it's the same or not.

Sound like you need to add a relay that can handle the higher current... Preferably before you fry the replacement module!

[DRIFTINGmy85]

It is simply a relay?
I could add another one in it's place. All I need to do is figure out what wire is what.

I guess you could lube up all the moving parts to help ease the load...

you can add a relay that takes the standard signal across the low power side to turn it on and that way the module doesn't see the high current load. I'm not sure about the wiring on it but it's pretty common when you have applications with higher current. It's the same reason you use relays when installing electric fans so the standard wiring doesn't get burned up...
