1999 GMC suburban Brake lights only work when you manually use electric trailer brakes... pushing on brake pedal brake lights flicker and go out right away?

Try checking the wires on the harness going to the brake switch. I have the same problem, and there was a short in one of the connections. the bad thing about it, it is hard to get to with out dropping the column. Hope it helps.

Cruise control On my 1999 Suburban keeps cutting out, I hear a relay click off and the vehicle looses the criusing speed de-activate on its own. Which I would live with BUT NOW! I hear the same or similar...

Have it checked for DTC'S - diagnostic trouble codes ? Does the battery goes dead with the vehicle sitting overnight ? Where do you hear the clicking noise coming from ? Under the insturment panel ?
Test the electrical circuits for those systems using voltage drop . Do you know how to test automotive electrical circuits using a DMM - digital multi meter and a wiring diagram so you know where to test at . Find out what this systems have in commond , a B+ voltage supply or do they share a common ground point ! Looking at a wiring diagram i see the cruise control and 4X4 transfer case shift control module share a common ground G- 103 & G-104 . Plus the 2 or 4 wheel drive light is controlled by the transfer case shift control module G103 (Gas)
On the right front side of the engine, near the thermostat housing
Power and Grounding Component Views in Wiring Systems
G104 (5.0L/5.7L)
Backside of the right cylinder head

It is more then likely a loose connection ( ground ) maybe ! But without testing this would be just a guess !

Free wiring diagrams here Click wiring diagrams , not TSB'S Enter the vehicle info. year , make , model and engine size . Then under system click on the one's your having problems with . Start with testing B+ at the battery engine off ,then running ! 12.6 V engine off is a fully charged battery , 13.1 to 14 .1 + is good charging voltage . Watch the videos an test the circuits . Good luck ! You would like to know what the problem is for sure not guesses .
