96 Suburban Electrical Issues
I have a 96 half ton chevy suburban that has electrical issues. When the air conditioning is on my anti-lock brake and regular brake light will come on and disappear seconds later. The fan will shut down for a few seconds then return. On a road trip this past weekend we got new behavior. Whenever the fan level was changed or the air turned on/off, it would disable my cruise control. Not just temporarily it would only return if I shut the vehicle off. Even then it was only a few minutes before the sequence would happen again. Here's the sequence: 1. Change of internal fan/ac settings, 2. anti-lock brake light on, 3. second later regular brake light on, 4. 2 seconds later anti-lock light off, 5. regular brake light off. Tried to use the cruise control then my tackometer and speedometer dropped to zero and reengaged to normal position. Help,

Re: 96 Suburban Electrical Issues
First thing is check the grounds....internittant wierd electrical problems are difficult to diagnos and many are caused by bad grounds.
Also check the battery cables for corrosion.
