Hello, I have a 1989 XJ6 and are having problems with the right turn signal. when i turn the right turn signal on everything is fine ,till i step on the brakes, the indicator on the dash blinks faster , the front right turn signals operate great, but the rear signals quit ( no blinking) I have changed all the bulbs with the correct ones, checked the grounds for contact, Does anyone have any ideas where to go from here, Also what is the difference between a Rear lamp Relay Module and a Lamp Control Monitor. Thanks

 

You may not be posting in the right forum. 1989 suggests you have an XJ40. Unfortunately multiple models get the XJ6 label even though they are very different cars.

 

Hi, you will get better help in the XJ40 forum section.
This section is for the XJ6 until 1987.
