Replacement for the poorly constructed original GM switch
937412
Had to replace the poorly-built ACDelco OEM switch  module when the rheostat (dimmer) failed; apparently a common occurrence. Says more about GM/AC Delco engineering and quality than I ever could. Truck is not even 7 years old and the friggin switch failed. The marginally better news is that this was dead easy to replace - took all of 5 minutes. So they might be crap components but they are easy-to-replace crap components. Deducted 1 star because I have every faith that this one won't last long either...

Blower switch died.  So I ordered this part, and "ACDelco 15-72547 GM Original Equipment Heating and Air Conditioning Control Panel with Rear Window Defogger Switch" (the entire assembly) as I was unsure if just the switch was compatible.  Sure enough, remove the assembly from the dash, one small screw and a couple of clips and this switch replacement was easy without needing to replace the entire assembly.
Warning.  The clip plastic is REALLY brittle.  Even with caution, 2 broke.  But the screw still holds the switch in place with the two remaining clips.

I have a 1999 GMC Yukon and a 1999 Chevy Suburban.  This is a direct replacement in both.  Check your models, years and months of manufacture.  And remember, the models changed in 1999.  My vehicles are sold as 1999's but were made in Sept and Oct of 1998 and searching 1998 parts gets me the correct model every time.

Had to replace my old hazard switch as the relay was busted and would click randomly (a common problem) the replacement I received in addition to having visible rust, has the SAME PROBLEM. I broke my old one pulling it out of the car, and I can't pull this one out until I have a new one or my turn signals won't work.

I installed this a while ago as the front sensor on my '96 Geo Metro and it has worked well.  This generic sensor is much cheaper than buying the same sensor with the connector specific to my car.  All I had to do was cut the connector off of my current bad sensor and reuse it by splicing the wires from my connector to the wires on this sensor.  I soldered the splices and sealed them with heat shrink tubing.

Updating this review because this sensor failed after about 8 months of use, also the direct replacement model that does not require splicing the connector is now cheaper than this one so there is no reason to get this one (for 96 metro at least).

Switch and harness were inferior.  The switch doesn't work!  Once installed, lights are bright.

the switch of on/off is not working anymore, but luckily it is on position, so now i have to pull the wire instead :)

The small key ring hold on the bottom of my original GMC key fob had broken so I needed a new one. Purchased this from Amazon for about $8. It's simply an empty shell. Northing fancy. You crack it open with a knife or tool to pry the two pieces apart. Then you simply take the circuit board and battery out of the old one and put it in the new one. The only reason I didn't give this a higher review is because I used the replacement key fob's buttons instead of transferring the buttons from my original key fob. The original key fob still had the graphics on it even after 3 years of continuous use. The replacement fob's button graphics wore completely off after just 4 weeks of sitting in my pocket. Other than the graphics wearing off the functionality is fine.

This did not properly thread into the door jamb of my standard cab 91 gmc sonoma.  The door would not close without damaging the switch.  In the end I just cleaned and reinstalled the original switch.  No issues now.

Direct replacement for the part that went out on my Whirlpool Duet dryer, model GEW9200LW0 (zeros-not o's). Heater element would not turn on, and testing showed the heater control board (or whatever it's called) was not working, specifically the relay was bad (bypassed relay briefly and heater element heated up). Rather than pay roughly $200 for a whole new board for a $10 part, I bought this and (my brother) carefully unsoldered old relay, and put this new one in. Crossing my fingers the whole time. Fixed the problem and has been running fine for several months now. I wish the factory had made these plug in instead of soldered, but then they couldn't sell us a whole new control board I suppose. Mind you this dryer is 14 years old, so it did last a long time prior to breaking.

I ordered this unit and ended up returning it.  Not for defect per say, but I realized that Delphi is the only manufacturer at my time of purchase (Oct/2011) that has corrected an electrical problem with this model fuel pump.  It was $30 more when I purchased and included the new wiring adapter harness with a little heavier gauge wire.  So, it won't be exactly plug-n-play for this reason and will require minimal wiring work splicing it in. The original design flaw was inadequate wiring shortening the life of the pump.  When I look now at the product image I can see the difference on the connections.  Btw, this part is for the four door model GMC Jimmy and there is a different model for two door model.  For goodness sakes, on an ugly job like this, stay away from the cheap crap garbage that may not even make it down the street as I do know some horror stories.

Like the title says, the D1843A is a new revision (according to my GM dealer).  I'm sure this will work fine, but get the correct switch.&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/ACDelco-D1843A-Switch-Assembly/dp/B0016HURFO/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">ACDelco D1843A Switch Assembly</a>

Direct replacement for the original part on my 2003 Eurovan. Installation was a little tricky because of the tight location but I got it in with minimal loss of coolant (most of which soaked me). "Check Engine" light for ECT sensor fault is now gone, so the computer must be happy -- and so am I.

UPDATE: Well, my rating just went south (from 5 stars to 2 stars) on this sensor. My "Check Engine" Light returned and now it is clear that this sensor went bad. I ordered another one from a "Real" parts store and now I see that this one was a Chinese knock-off. Not good. On the plus side, I'm getting really good at replacing this part..

This switch is one of the very dumb design decisions that Ford Motor company made. Instead of a decent real switch, they decided on a plastic covered depression switch. The plastic over time gets brittle and then breaks making use of cruise control impossible. This replacement part is just another Ford thing. However, it works well and I suspect I won't have the car by the time the plastic breaks again. The price for this Motorcraft part was MUCH cheaper than the dealers.  It is the same part.

Looked OK at first.  It installed easily and fits like the failed original it replaced.
After I got it installed, I noticed the auto-down feature doesn't work.  The switch, labeled auto, doesn't have an auto position to it despite saying it on the switch.  Normally you push past the initial resistance in the switch, hear a click, and the drivers side window goes down all the way on it's own.
This switch won't do it.  I was disappointed, but to me that's not a big enough deal to tear the door panel back off and return, etc...

About a month in, the lock/unlock function started becoming difficult to activate.
I'm at the point where I'm pressing it 2-3 times just to lock or unlock the doors.  Seems like going from lock to unlock, back to lock will cause it to work.  Something broken and loose perhaps.  Engineered to OEM specs would mean cheap brittle plastic like my dash  LOL.

I've had this switch installed for a few months now and it's working great.  Time will tell if it's durable.  The original switch stopped working after 80,000 miles - hopefully this new switch will last just as long or longer.

I have had to replace this switch 3 times in the past 5 years, hopefully this new product number is better quality that the previous ones.  This one worked and fit properly and was less expensive than thru a local distributor.
