If you see a change, they are probably getting the signal but the LEDs are fried. You can unbolt them and plug them to the other side to test them.

The normal operation is that the light comes on when braking, but if signalling, the light doing that will blink while the other stays on solid.

 

Sienile! Thanks for your reply, sadly I’ve got it on both sides left and right. Listening to your advise think buying a new unit would be wise? Did already the trick with contact cleaning with no result. As I have the car for couple of months, think bought it with this issue. Never been noted (mot) as all work fine seperately I suppose, cheers Menno

 

Since both are busted, test the circuit with a multimeter. You should get a full 12v on the circuit.

 

Thanks Senile!
Thanks for your advise and your file! its been some time but after long waiting time my new taillights arrived yesterday. Sadly both new lights do the same thing! Only when braking and indicating one solid light, but faint 1 millisecond spike interruptions (on 1 second blinker frequency )when look closely. yes all lights work seperately, but combination brakelight and turnsignal together, the brakelight overrules the turnsignal both sides.... checked all leads with multimeter ... is culprit the TiPM?

many thanks Menno

 

Sure sounds like a TIPM issue at this point.

 

Thanks again! Just your thougts please, if codes match (68217405ab) can I use a Lancia voyager / Chrysler T&C tipm as they have different tail lights ( found one in germany )

 

And last question, does Antoine know de location of connection C104 ? (Red circled in attached photo)

 

TIPMs should auto configure once installed. Just leave the key turned for a while before starting the first time.

 

Thanks again Sienile, fingers crossed ordered one from California. Connection C104 in above picture any clue were i can find its location? cheers Menno

 

I'm not sure, but I think it might be one under the TIPM or just inside the cabin behind it. Check wire colors and locations to match it up.

 

Merry Christmas from Holland, Sienele!
New Tipm arrived out of California, fitted but sadly still same issue.
Is the PCM also involved in signal proces?
Bought now already new tail lights and a TiPM
when installing the new tipm I checked all connecters underneath it. all in shiny nice condition. Still didnt find connector C104 in photo above.
Anybody got a clue where i can find this connector?

Problem still is only when brake lights are on, the turn signal is overruled and not blinking anymore, only a very faint milisecond interuptions is seen if you look closely (in the frequency if the turn signal) left or right, and with warning lights both lights do it.

many thanks for your efforts

 

Update: problem solved!
after long research found cut wire and Some causin poocky soldering undernead tipm and odd connections. I retuned it back to original what solved the problem. Thanks for all advise.
