I'm glad that Dorman can tell you what their products fit...

I had a a/c function knob go bad on our 1996 Sable wagon.  I actually printed out a replacement on our 3D printer, but that didn't work well (designer error).  I ordered this trio of knobs.  Sure you probably get two you'll never use, but the third one will be an exact duplicate of the original.  Nice to be able to keep the car running.  Just make sure you check for compatibility.

I wanted to give them a 5 star rating after I installed the passenger side until they DID NOT fit on the drivers side and I wanted to give them 1 star - the average is 3 stars.  Dorman claims these fit perfect.  They do, but only one side of your vehicle!  When something only fits on one side - its DOESN'T fit on the other side!  I replaced the seat heater pads on the seat bottom and seat back.  I ordered both Dorman parts (641-105 & 641-106) through Amazon.  Obviously with Amazon, great price, great shipping, etc.  Check out the You Tube video(s) I will upload shortly (under 'debandpete') on the actual problem/process with these.  One side went in without problems.  There are tons of videos on You Tube and instructions with the seat heater pad.  The problem is that since they are 'universal' and the wire does not come out of the seat heater pad in the middle - it comes out on one, which means that on one side of your vehicle it will reach the connecting electrical coupler underneath the seat, BUT on the other side of the vehicle it will not reach.  There are people that suggest pulling the supplied 'sticky tape' off and putting it on the other side.  DO NOT do this.  The seat heater pads are directional and designed to heat mostly in one direction.  If you look at the design close enough, you will see that.  The instructions even tell you to not put the tape side up to the upholstery.  If you flip the pad over and put the tape on what was the top and is now facing down, the heat will be going into the foam and not into you.  The answer ended-up being to simply route the electrical cord out the opposite side that the factory cable was routed through.  If both the seat bottom pad & seat back pad are both on the wrong side, then they will still plug into each other as designed and still reach the GM connector under thereat frame.  Sounds simple but wasted a lot of time, phone calls and of course happens on the weekend when Dorman was closed.  Dorman SHOULD add a simple paragraph to their instructions explaining this process.  Check out my You Tube video shortly!

Dorman used to have a quality name in aftermarket replacement parts, now I am not so sure. The last two Dorman products I purchased had quality issues and had to be exchanged. In this instance I received the first one and inspected the coolant ports near the EGR passage, the surface was very coarse and had excessive flashing from the molding process. I requested a replacement, the second one was somewhat better yet it was very coarse too so I didn't want to risk it not sealing, as many of the one star reviews have stated. I sent it back and purchased a slightly more expensive Delphi replacement plenum. It was smooth as you would expect on the sealing surfaces. I was pleased with Amazon's service, disappointed with Dorman's product.

Overall, it fits my 2004 Honda Accord.  However, I noticed that there was some lack of attention to the fit and finish of the small bracket that holds the wire sleeve (when you take out the old handle assembly, you'll see what I'm talking about).  So I had to disassemble the Dorman unit and take a file to shift a screw hole to one side to make it fit.

All in all, I would buy it again.

I'd read a lot about these things.  I opted to try them and am happy with what I got.  They fit well and the casting doesn't look any worse than anything else that came stock under the hood.
Now pulling out the old pipes and putting the new ones wasn't necessarily fun, no fault of the parts, just tight quarters.  At least now it's done and I don't have to worry about leaks again.

No mysteries with this part. The money was right. The shipping was right. And the fit was, oh, so nice. If I had a wad of hundreds to burn through I would have hired someone else to put in OEM stuff, and gone out to a long lunch whilst they paid attention to the "sharp edges". The edges you shouldn't be sticking your fingers in are sharp. Go figure! The project as a whole is a pain, even without fingering what you shouldn't, but at real mechanic labor rates I figure I did a good portion of a weeks pay in a long half-day. Nothing wrong with that, I guess you could say. And if it craps out again in another six years I guess I would go at it in the very same way. And leave us not forget to mention, in our overheated political climate, that the biggest portion of Dorman's footprint is right here in the U.S. of  Fuggin Aye! Hey, hey. Yay! Buy some even if you don't need 'em, they're Great!

The Dorman part is a hair shorter than OE (Grand Prix GT), but it does fit well.  The heat shield on this part covers more than OE and the construction of the part seems very solid.

It comes with 2 gaskets but you only need the one for the back manifold, as the front is a metal-metal seal.  I used a wire brush on a drill to get the paint out from the inside of the front flange, and for the rear was careful to make it snug but not over-tight.  The flanges on the back should not touch, but just put pressure on the donut to let it do it's job of sealing everything.

The paint on the pipe will smell terrible for a day or two then go away, but man is it stinky for a while.  Overall I'm happy since the price here on Amazon was less than 1/2 what Autozone wanted for the same part number.

It's nice to see a company that makes large sizes available in different widths.

Properly made, not like the flimsy "Dorman" brand. It come assembled unlike Dorman brand, and it's packaged very well. Cheap enough even though it doesn't come with gaskets; even after buying gaskets still cheaper than Dorman and made in the U.S.A.

What can I say; it fits and works - made by a reputable company and the price was very reasonable.

as long as you know your size and know the 501 fitment, it's smooth sailing.

Dorman HELP! 614-632 C Series Universal Quick Boot Kit is only for the outside cv joint only , I bought this because I thought it was for the inside one, lucky for me because it is larger than the inside one I was able to leave the split inside one in place and install the new one over the old one only because I had enough room around it. I would recommend you get the right one for the inside one..

I found this company's products recently and was impressed with my first purchase. Since buying these I am even more convinced that there are differences in manufacture and fit ... these are outstanding.

I am glad I purchased this replacement. You can tell that it is beefed up from the original part. Hopefully it will last longer. I love the fact that it comes with everything you need. It has been on for about a month now and seems to be perfect. I have had good luck with other Dorman products in the past and this one seems to be excellent as well.

I have purchased a number of Dorman window regulators to replace OEM parts for friends on various models of vehicles. I have always been happy with their products, save a few motors being slightly louder than factory. This one I purchased for one of my personal vehicles, this review was for a 2002 Jeep Liberty, front driver door. It has been almost a month and I'm mostly happy. Regulator install was about 35 minutes, but l found, like another reviewer stated, the trailing edge of window now protrudes approximately one half inch with window down. This it's slightly disappointing since I've not had any issues in the past. It seems to be an engineering flaw. Although not a deal breaker, this should not happen from a company who specializes in this field. I would drop to 3 and a half stars if possible, or even an apology from Dorman for letting this slip through quality control. But all said,  it is still a good product. I hope this review helps with your decision knowing the defect that it comes with.

I was having some horrible squeaky sounds coming from my drive shaft. After more research I found the problem to be the Center Support bearing in the driveshaft. I ordered another, cheaper knock off brand, and that didn't last for but a little over a year. Well, lo and behold, I needed another, so I gave the Dorman brand a shot. This one is still holding up, and looking under my Tacoma the other day, I was glad to see the rubber is still holding strong, and it looks to be a winner! If i need to replace this again, it will be with a Dorman. Very happy indeed!

Fit like a glove, just make sure you measure the old one before you decide which one is right.
