I have a 2003 Chevy Avalanche. After getting my A/C replaced by another shop, the headlights would turn on and off intermittently. It was strange behavior that I've never seen before. I took it back to the shop that did the A/C work but they weren't much help and wouldn't fix it. After making many attempts to have it fixed at other shops, no one was able to fix it or would tell me that they couldn't get the lights to mess up. I dealt with this for over two years. I simply pulled out the relay switch on the fuse box so the lights wouldn't come on at all. Chris at Lakeshore Automotive was suggested by a co-worker so I took my truck to him. Within 2 hours he was already contacting me letting me know what the problem was. It appeared that my main fuse box had a short. It was replaced and I had my truck back in 2 days due to parts being ordered. I am very pleased with the service I received. They kept me informed and were within my budget.
