Need help with my signal lights..

[guruerror]

According to this site (http://parts.nalleygmc.com/showAssem...=0&modelYear=0) part 12177236 is a "RELAY,ELEK BRK CONT IND LP".

According to the 2003 Manual (http://www.manualowl.com/am/Hummer/2003-H2/Manual/689), page 6-66 the Electronic Brake Controller Battery Feed (RTD) fuse is located in the Underhood Fuse Block.

I hope that gets you going in the right direction.

So i was able to fix the problem. The fuse box behind the panel on the end of the dash has a big relay on the inside. Its called the flasher relay. Replaced it and the problem is gone.
