a garage mechanic would move the tires to see if there is any slop in the tierod. and some times its easy to see or feel. the parts you can get at any parts store and prices vary on brand and quialtiy. as for labor most garages charge by the hour and it will take an hour to do both sides and then you will need to get the car aligned. my suggestion is if you take it to an alignment shop and they don't need to be done they will tell you. at least if they know what they are doing. some shops will do better work then others. when you find a good one or hear of one. try that one. some shops will inspect at a small price depending if you don't need an alignment. and most will change the parts and do the alignment and I suggest getting the old parts and see the wear for yourself. some can even show you before the work is started. but some shops don't allow customers in the garage so each is different.

According to Don r : "The relays are in the fusebox under the hood. There's a fusebox on the driver's side kick panel, there's another one behind the change drawer on the left end of the dash and there's another fuse and relay box behind a panel on the passenger side below the dash. Chilton's Auto Repair manual will show you these. Look in your owner's Manual too. " According to mtran2988: "So I know this sounds very silly, but I had this problem for a while as well. What I did to fix it for a while, was open the fuse box in the car (under the steering wheel) and remount the fuse for the power lock. After that all the door's locks started working again. Like I said, i know it sounds very silly... but that's what I did and it started working. I feel like trying this might save people some hours. Mind you, I don't have very great technical knowledge of the mechanics of a car.. just a persevering DIY'er." I hope that helps!
