I have read that people have had others check the relays. Swapped relays and nothing has changed. At this point I am wondering if it is Software related, Module related, or controller related. I need help with the issue cause at this point I am at a lose.
One quick side note, this Tahoe is an Ex Boarder Patrol vehicle. The ECU still has the tune from when it was an Active Law Enforcement vehicle. I don't think that would play a factor in any of this but any side piece that are computer related I thought I might jot down as it might aid someone in helping find a solution to this issue. Chevy CSR can you help please?
