hey evryone,
I have a 2002 Volvo V70 2.5T. Both rear brakes lights stop working intermittiently. They'll quit working for a few days and then just start working again. This is accompanied by a "check stop lamp" message on the computer. The center brake light over the hatch continues to work all the time. I've checked the fuse and replaced both bulbs even though they were all good. Does anyone have any suggestions as to what I might check next? Thanks for your help.

 

Possible brake relay in the trunk cargo area on the left side. Swap out fog relay and see if it fixes problem if it does you know its the brake relay. Fog relay and brake relay are the same.

 

May be a recall - brake light relay replacement Recall Campaign No 131 Brake light relay. certain model yea 2002 v70 and v70 XC vehicles. Hight position tail light not affected.

 

I have this same brake light problem with a 01 S-80 and I can't tell which relays are which and have no manual other than the owners manual which is not very helpful as it doesn't list the relays. Any help would be appreciated especially if I could find out which relay it is. Thanks everyone, I am a new member and just found this board. Dave
