When the vehicle was brought in it had a power steering noise and no a/c. Power steering requires replacing the pump but you did'nt want to fix that repair because of the cost you wanted to fix the a/c instead. When we started working on the a/c repair we found that someone put stop leak in the system which automatically bumped the price up because the a/c parts were clogged from the stop leak. We did change the oil but forgot to bill you for it on the original bill and told you we would bill you the next time the vehicle was brought in. As far as the light bulbs the book says you have to pull the bumper cover off and remove the headlight assemblies to get to the bulbs usually a body shop would do this repair but i went ahead and attempted it with out removing everything the book called for and could'nt get my hand in there.
