Hello everyone,
My dad is having trouble with his car that just started recently. He tells me that whenever he touches the brake there is a power voltage reduction to part of the dashboard which sets off a buzzing sound and loss of gauges. Has anyone had a similiar problem with their car and how did they go about fix it. He told me that someone would attempt to trace the problem for ~$1000, is this a fair price. My dad thinks it might have been from heavy rains as he doesnt know what else could affect it.

Thanks for your help
