What would a reasonable charge be for a window regulator replacement be? Labor?

even though I ordered the part number that He told me to order? and since when does it take anyone 1 hr to remove a door panel... according to the time it takes on the labor side... his own system... the whole replacement takes 0.8hr worth of labor.. and he did nothing... so he charges me a $46 for a diagnostic... when i told him already it needed to be replaced... then an additional $96 to tell me the part that was in a box and he had in his hand was wrong? so he couldnt see that the part that His guys had me order was wrong.

not until he removed the panel. he had to re install it too. i know you are frustrated and i dont blame you but even in my shop, if you want to provide your own parts, you pay if it is wrong. talk to him about it rationally without sarcasism and see if he will help you out. he should if he want s to keep you for a customer. a good business man always wants to keep his people.
