HI,
I am sorry that you have not been helped yet.
So all these parts tested bad? If so, then I suspect a short in the wiring system taking these components out.
If these were just replaced on a guess, then it is time to do actual diagnostic testing instead of throwing money and parts at it.
If you have a voltmeter and a diagnostic scan tool with body function testing, as well as decent ability to read wiring schematics, let me know and I can walk you thru testing

Only resistor cracked everthing else was still good
Expert:  Eric replied 1 year ago.
HI,
Resistors usually only do that due to a short. You need to trace the wiring back from the resistor for any cuts, chafing or breaks

I have 2 part cars with cracked resistor & DTR worked.
Customer: replied 1 year ago.
checked out wiring found no problems could it be the BCM?
Expert:  AZTechBrian replied 1 year ago.

hello. The resistor cracking is a common problem on your car and is usually the cause for inoperative lights. there is a TSB on it for your car. Did you replace the resistor with a new one, or with one off of one of the parts cars? Do you have a B2600 DTC?

Customer: replied 1 year ago.
a brand new one
Expert:  AZTechBrian replied 1 year ago.

Do yuu have a B2600 code?

Customer: replied 1 year ago.
no codes
Expert:  AZTechBrian replied 1 year ago.

OK. and you checked out the resistor connector good to make sure that the terminals inside the connector are not corroded and making good contact? It's very unusual for this issue to not be caused by the resistor. Is the connector in very good condition? absolutely no corrosion on the terminals?

The resistor came with the new plug I replace the plug with it

Ok. One last question before I throw this question back into the pond... you did't wire backwards, right?

Customer: replied 1 year ago.
plugged in the original plug-in cut the wires and wired up the same way it plugged in
Expert:  AZTechBrian replied 1 year ago.

Ok. I hate to do it, but i'm going to hand this off to someone else. Hopefully you get this figured out soon.
