From my experience, chain hardware stores (eg, Home Depot, OSH, etc) readily refund my money I when I try to return their merchandise--provided that it is still in good condition and I show them the receipt. Until recently, I haven't really done much work on my cars other than oil changes. So, I've never needed to return anything to an auto parts store before. Do chain auto parts stores (eg, Kragen, Pep Boys) typically accept returned (non-special order) auto parts? I'm 75% sure my washer control module needs to be replaced, but I'm trying to get a feel for whether or not I can return the new module if the old one isn't broken. Thanks.
