Mondial Brake/Stop Lights not working!

Hello to Farnborough!

If the fuse is good, here are the other things I would check:

Pedal switch, as you have indicated.
Tail light relay
Harness connector to fusebox
Grounds to pedal switch and lights.

I have a 3.2, so my relay is in a different place, but check your manual.

Any electrical malady is a factory feature of the Mondial, usually related to poopy connectors. When I have a flat tire in a Mondial, the first thing I check is the fuse box.

Good luck and best regards,
Russ

 

In my t there is a connector for the brake lights right under the steering wheel. Maybe they are loose ... ?

 

Call the other Mondial owner..... whose lights won't go out!

 

your thought that the diagnostic light should come on is correct. But you are also correct that diagnostice lights have been known to fail good luck, I am dealing with the opposite issue - lights always on - which is good for keeping people from following too close

 

Ian,

Correct, plunger type - however there are two different types that are fitted to the Mondial that operate on the same principal, but in a different way.

If you need to replace the switch, the differences are obvious, one type has two terminals and the other has four terminals.

thanks for the info, but I got myself in the footwell and could not find the switch - please don't laugh. all I can see is when the brake is depressed is a black cylinder like mechanism that pivots on a shaft, there seemed to be a mechanism on the back side that pulled from the firewall when depressing the brake but I could not really see it. I would also add my problem still remains the brake lights staying on for most of the time but now every couple of times the brake lights will go out when I depress the pedal (don't you love these cars This leads me to think its more the relay but going through the wiring diagram for the main box I am not sure which relay it is. I also know that they are relays under the dash and pass footwell but not sure I see these in the wiring diagram

On my 83...
The switch came out of the silver casting from under the hood. There's a funny looking white plastic nut that goes up under the dash on the inside where the switch comes through... it's a real pain to get back on. I didn't know about the plastic nut until I found it under the dash months latter. PM with a phone # and I'll try to explain how I got mine back on.

 

PM sent, thanks, what is wierd is I read those desciptions of what should see under there and I don't see any of it, maybe I am not enough of a contortionist

 

Here is where my 85 Mondial Cab's is located. I wouldn't worry too much about the white nut that falls off. It is just a lock nut. The switch is threaded into the foot pedal box. You can do one of two things to prevent having to get back under the footwell.
1. Place the white nut on the switch before threading it into the silver box. This may prevent you from properly adjusting the switch to pedal distance. If so the brake kights will be on all of the time. If this happens:
2. Use a couple of washers as spacers on the switch before you thread it in and make sure you thread it in snugly. This takes a little trial and error to get the switch plunger to brake pedal correct, but it beats trying to get that nut back on under the dash.
Hope this helps.

 

Thanks! I see that (the black thing with two wires center bottom of your pic), I think mine is white with 3 or 4 wires. I did not think that was it since it seems so far (higher) form where the brakes are on the inside. Where have you guys gotten the replacement switches.

 

I am a little embarassed to admit it, but the switch you see in my car is a GM switch that I purchased for $1.99 at Auto Zone, and my car was a 4 wire system. I did a little testing and found that two of the wires are for the diagnostic panel on the console. I jumpered those two wires together since as I recall they have nothing to do with brake light operation, but cause the "stop lights" warning to illuminate if the brake light switch stops working. Oh yeah I did have to buy a die and rethread the GM switch to fit the pedal box thread, but it was only a couple of bucks.
I was in a hurry and when I checked I remember the stoplight switch as being pretty pricey so I went with a quick and dirty approach and never got around to fixing it with an actual Ferrari switch.
It wasn't until I saw this thread that I even remembered that I had done this. Guess now I'll have to fix it.

 

thanks, got home and with a mirror I could see where the switch was, there is no way to get at it from the inside but mine only has a nut on the outside, I got it off easily. I called rutlands and they wanted $83 bucks for this little switch, I will see if I can get an alternative. will posts pics shortly

 

I replaced my brake lamp switch in 2002. I paid about $78 for it then - after quite a bit of checking, so the $80 price is not out of line. Although there is a nut on the outside, there also is a plastic one in the footwell behind the pedal. It is rather high up on the firewall, actually above the pivot shaft, if I recall. that is why continuity appears scewy. It is actually backwards.

Replacement is a two-person job. Measure the length of the protruding part of the old switch before removing it. You can then use it as a guide for installing the new one. Get a helper for the outside (under the hood), contort yourself in the footwell and place the inside nut over the through hole in the firewall (you may need to hold it in place with a pair of pliers) and have the helper screw in the switch while you hold the nut stationary. Adjust (screw in or out) the switch until the brake lights come on when pedal is depressed and go off when it is released, then screw on the outside nut (acts as a retainer) and plug in the wires. Good luck!
