I can look for you on Monday.

What is the part # on yours or is it a Base or Premium (w/electronic cluster) BCM?

1990 Chrysler Le Baron 3.0 Cabriolet Specifications
VINnr: 1C3BJ4531LG473146

Body Controller, (Base) Stamped 4503112

however, i swapped from analog to digital a few years ago and to do that a premium BCM was required.
i can not find a number on my BCM, but i believe there was a number range 4020 in it orso.
is this helpfull?

well, the flasher won't work.
the turnlights are working but not the hazardlights.
the relay is also shorter then the accisting one.
i took the the relay from the donor cat, which is exactly the same blue one, but that does not work also.
now i start thinking about a loose wiring orso.
fuses are okay.
i keep looking and posting back to you.

There are two power feeds into the Dual Function (Hazard/Cancellation) Switch.

BK/PK wire from fuse #6
BK/WT wire from fuse #28.

The solid BK wire is ground.

Here is the Dual Function Switch test for the Hazards.

The pinout for the Hazard/Cancellation switch is at the top right.

Circuits L05 and L09 are Power in from Fuses 5 and 28.

Circuit Z01 is Ground.

okay, in that case, i have ground aswell as power on the switch on the cavitys.
i replaced the switch just to be sure with a spareone from the donor car, a working switch.
also tried 3 different relays.
fuse are okay

With the key on check for power on the PK/WT wire at the flasher with the T/S on and then with only the Hazard Flashers on.

The wiring is getting me confused, seems Chrysler took a long way around what should be a simple system.

With the key on and T/S and Hazards off what is the voltage at each terminal at the flasher? (Flasher must be plugged into the connector)

1)RD/LG
2)BK
3)PK/WT
4)DB/PK

Those numbers do not seem right, what are the voltages at the Cancellation/Hazard Switch connector with the key on/flashers off.

1)BK/WT
2)TN/LG
3)LG/WT
4)PK
5)BK
6)PK/DG
7)RD/LG
8)DB/PK

4)PK: NO PINK WIRE?
5)BK: 01.2
6)PK/DG: .291
7)RD/LG: 01.3
8)DB/PK: 01.3

Are you sure your meter is on the right scale (20 volt scale) and that you are connected to a good ground?

At the cancellation/hazard switch the BK/WT and BK/PK should both read 12 volts with the key on.

BK/WT: .80

BK/PK: 11.44

I assume that you meant PK/WT where you wrote 4)PK ?
The BK/WT wire is a 12 volt power feed from Fuse #28 and should read 12 volts with the key on.

Do you have 12 volts in and out of Fuse #28?
