Well this is my second time in for this, before when it melted the washer and black wire. This time they put in the harness/fuse. All it is, is a 4 inch long wire which plugs into the washer and the other into the harness. It must have took them 30 seconds to do it. This does not help it from happening again, just protects it from fire or melting wire. Piss poor fix if you ask me. But the bigger problem was a oil leak near the rear main seal. They were going to put in a new seal but decided to put some dye in the oil to see if it is pourous leak in the block. So either way it is going to be a big job. Will know more when I take it back in around 200 miles for them to see where exactly it is. So far nothing but troubles for my 07 Denali with only 5000 miles.
