Standard Motor Products RU-572 A/C Blower Motor Switch

Works great in my 2002 Mercury Grand Marquis! Car wasn't blowing ANY air through ANY vents; thought it was blower motor at first (replaced to no avail), then popped this guy in (~1hr install time) and everything is cool again. Will report back if durability is an issue, but so far I'm a very happy customer!

This fit my son’s 2001 Lincoln Town Car. Fan would just stop for no reason, or go to full speed even when set at a lower speed. Removed one heater hose and a switch that has a vacuum feed and a couple hard lines and electrical connector which was in the way. Requires patience, and a special hose clamp tool came in handy. New resistor works great! All functions normal now.

Update . . . . IT only lasted about a year and quit. Now it only works on full blast high speed. POOR QUALITY! For the time to install it, they should make a quality product! ------------------------------------------------------------------------------------------------------------------------------------- I installed this blower motor resistor (they call it a switch here) along with a new blower motor onto my 2005 Mercury Gran Marquis. I removed one of the heater hoses to get access. It was a tight space to get the old one out and replace it, but was able to get it done in a couple of hours, including the blower motor replacement. I had to improvise tools to remove bolts from tight space. A sailor's dictionary would have been handy a couple of times to select appropriate swear words, but overall I think it was less work than removing the valve cover (to gain easier access).

I bought a 2001 Town Car two years ago. A gorgeous vehicle, but it had on/off problems with the climate control blower. I replaced the fan, but the problems continued. I took it to a dealer that kept it for 1 1/2 weeks and charged a ridiculous amount of money -- where it worked for a few days, and then the blower went out again. I asked the dealer to replace the blower resistor motor, part XW1H-19E824-AB. They said it's not available from Ford anymore.Installation: It requires a 1/4" socket set, a pair of needle nose pliersDisconnect the battery. The blower resistor motor is on the fire wall, directly behind valve cover on the passenger side. It's a black box with an red/white label on the front. There are two hoses that have to be disconnected and pushed aside to get to it. I removed one end of one of the hoses and pushed it aside, and completely removed the other hose. Once the hoses are out of the way, wiggle in the socket and take off the screws. You can then pull out the part, and then remove the connector. Plug in the new part, wiggle it back in its hole, fasten the screws so they're snug, replace the hoses, and it's done.Time: I spent about three hours, mainly because I found one of the hoses stuck. I had to use the hose remover to loosen the hose. Then it went fairly easy. Having done it once, the total time for installation should be one hour. There is a good description with photos available on "lincolnonline". Or look up, "how to replace town car blower resistor motor." It's a little tight in there -- a pair of mechanics gloves might help your hands.It's been three weeks now, and the Standard RU-572 proved to be a cheap fix. It wasn't the easiest fix, but anyone who can change a spark plug should be able to do this.

This is an update to my earlier review of this product.I contacted Midway Auto Supply (who sold me the part) about the part failure. They were excellent. They sent me a replacement part quickly. They gave full credit after I returned the bad one.So the product may have some quality control issues but Midway was very good and stood behind their products 100%. I have no complaints about the new part, and it has been in since December. As I said earlier, this part looks better than the original equipment. Solder joints are neater, the gasket looks better, and it just looks like a well-made part.-TVG========================================This is an update to my earlier review shown below, which was a five-star review from a part installed on 10/13/12.I purchased an RU-572 Blower Controller in October 2012. It worked perfectly for several weeks but over the course of this weekend it has rapidly deteriorated to the point where now it has only two options -- OFF, or FULL BLAST FAN ON. In other words, completely useless as of 12/09/12.I will be contacting Standard Motor Products for a new fan controller. I will be expecting it to be expedited to my house for free, or I will dispute the purchase with the help of MasterCard and PayPal, since I do not pay $45 for garbage.In any case, the new repair will take me at least an hour to perform, and as I said, it is not a particularly fun or easy job.Even if they give me a new one for free, I can't be certain it won't fail also. This is a job I frankly never thought I would ever have to do again. Clearly I am unhappy at this point.-TVG========================================PROBLEM:The blower in my 2004 Mercury Grand Marquis LS (automatic climate control version) for both heater and AC was erratic and annoying. The vehicle had less than 25,000 miles on it yet it seemed to pay no attention to temperature settings. It would randomly change from one inappropriate speed to the next, with excessive blowing that made it hard to even listen to the radio, let alone keep the cabin comfortable.QUALITY:This looks like a higher quality part than the OEM part I removed -- the gasket material is better and the solder joints look cleaner.DIFFICULTY LEVEL:This is a somewhat involved repair. I have replace the factory part on two cars now, and was able to complete my second one in about 75 minutes. You must first remove your firewall antifreeze lines (heater lines) to access the old part, meaning you must drain all or at least some of your radiator coolant first. I also found it necessary to buy a small 1/4" drive ratchet to loosen the lower bolt holding the old part in, since there is very little room for a tool here due to the right cylinder head's valve cover being so close to the firewall. A 3/8" ratchet with a reducer and a socket simply does not fit in there. It can be an awkward and uncomfortable repair, since you are leaning over a fender and cannot always see what you are doing.TOOLS NEEDED:drain pantowelscrescent wrench to remove battery cable from post and to open radiator petcockvarious pliers to loosen coolant line clamps1/4" ratchet3/8" ratchet w/extensionmetric socket setRESULTS:As soon as I installed this part (there are one or two helpful videos on youtube) the blower works great again and the car is quiet and comfortable. Steering wheel controls work fine once again.
