So I have a 1989 fc vert stock everything and all of a sudden I put the top down drive around and came home and it won't close!!!! It's stuck down!!! Checked fused it's fine I even replaced It with a good one and nothing . So I figured the switch is bad so I disconnected the switch to see if it was bad so I went through the FSM and looked for what pins make the top close and got a wire and connected the ones that make it go up but nothing! So since I had extra motors for the top that worked and hooked them up the top would open but still won't close!!! I don't know what to do now. I'm stuck

 

Check your hand brake switch.

 

Mine actually did the same thing once. I don't know why or what happened but all I did was just wait a little and tried it again and it worked and has since. Goodluck with the issue, maybe try disconnecting the battery and hooking it back up? Never hurts to try something easy.

 

In my '88 verts', there are limit switches at each top motor. One stops the motors when the top is fully open. The other stops the motors when the top is fully closed. Dirty or corroded contacts at either switch will prevent the motors from running. I believe the top motor control system is the same for S5s.

The body electrical section of the '88 FSM includes a wiring diagram of the system. It also has a troubleshooting table describing how to use the check connector at the right front strut tower. Checking for 12v at this connector can tell you whether the problem is with the dash switch, the parking brake switch or other. In my experience, the limit switches at the motors is probably your problem.

Good luck.

 

That was the first thing I check too the brake light come on in the dash

 

Is their a way you could walk me through that because I couldn't really understand. But I'll clean the limit switches and see if anything.

 

I in hooked the battery for almost 2 days because I gave up and couldn't figure it out and was like maybe it would do something but nothing

 

I can walk you through it. But it's not quick because to access the motors, you have to remove the complicated trim piece at the back of the door frame. Your short term 'fix' is the disengage the motor from the top linkage so you can close the top manually. This is explained in the owner's manual and in the Factory Service Manual.

 

It's all taken apart already and closed the top by hand . I had extra motors so I thought it's was that but it just put the motors down and won't close. So now both top motors are down. How do I do the method of the test connector to figure out what's making it not close

 

Easiest thing will be to download the Body Electrical section of the factory manual from Rotaryheads.com or Foxed.ca and work from the troubleshooting table. But since you already have access to the motors, it's probably just as easy to check the limit switches and the relays. If you have swapped complete motors, may it's not the limit switches. But here is how they function.

On each motor frame there is a small, cam-operated switch. Each switch has normally closed contacts. Power to open the top (well, to operate the relays) goes through the switch on the passenger motor until the top is all the way down. The cam opens the switch and the motors stop.

Likewise, power to close the top goes through the switch on the driver side motor until the top is all the way up. The cam opens that switch and the motors stop. If those switch contacts are dirty or the switch is broken, then motor relays can't get energized.

Sorry I don't have any pics of the switches.

 

Here is a link to a post I made last December. I listed the check connector test conditions. https://www.rx7club.com/2nd-generati.../#post11634414

 

Cleaned switches but nothing I'm going to try the test connectors
