I have a 1993 GMC siera 1500 The dash brake light came on after starting and I checked fluid level and E brake all ok . now its flashing three times and staying on longer on the fourth flash repetitavely . Had a auto shop look but only found a weeping wheel cylender, they and I think it could be a code for a switch,(abs presure)

I think you are right. It is either a 3, 4 or 13 code. 3 and 4 refer to the abs pressure valve. If it is a code 13. it is the Abs module at fault. Need to know if the single flash is part of the code or not. Does it flash 3 times and 1 long then 3 more and 1 long? Or does the long flash come up first. On some of the earlier ABS systems, the long flash was part of the code. It is hard to rell for sure without seeing it in person.



Being way2old is why I need help from younger minds
