2nd Gen Non-Engine/Transmission another brake/abs lite question......

[shendren]

my brake/abs lite flashes on when the truck is warm and running down the interstate and i hit the cruise button.



the rear wheel sensor is fine.



yesterday, i switched from floor to face on the hvac controls and the lites flashed again.....



this seems to indicate i have a vacuum problem of some sort. can the vacuum system be tested for leaks?



any comments would be appreciated. thanks. scott.

I dont have a vac problem but i remember reading that the vac line under the driverside battery gets eaten up and begins to leak. The cruise box is under there also. Might be a good spot to check. I am sure that you could get a vac pressure guage and hook it up to that line and see if it is pulling the recomended pressure. Good luck!
