Hi, Im not totally sure but I think the 3rd stop light is different on our UK blazers to the US models, i ask this as mine isn't working and needs replacing. The light is mounted onto the actual top glass (see pic) not the body, the wire then passes via a grommet on the body this gets worn every time the glass is opened up an mine has totally worn to breaking point ,thus I need a new lamp with harness atatched.

Are all Blazers top glass bottom fold down rear gates?

 

well im not sure what year your blazer is, but my 96 have it mounted to the top of the glass just like that...my 97 & 98 have it mounted in the roof so if your is 95 or 96 then yea its the same setup

Hi Thanks, mines plated 99 but GM imported a big batch in 97 that took 4 years to see (Japs, Jeep, and Land Rover have the market sewn up here) so may be built in 97, will any 3rd stop for a Blazer fit off e-bay, limited to spares here have to order from USA.
