2013 Chevy Malibu Windshield Wiper Relay #5
My windshield wipers stopped working on my 2013 chevy malibu and this relay fit and works perfect! Exactly what I needed and glad I didnt have to take it in and have it diagnosed for $200, saved about $185! Thank you for your awesome product! 🤩

Another quality OEM product by AC DELCO (and not just for GM vehicles)
These relays worked perfectly for my 2007 Can Am Outlander 800 ATV. I needed to replace a failing fan relay on my ATV. I bought two and replaced both the fan relay and the ignition relay. They fit perfectly, and since it's AC Delco, I am confident I will get many years of trouble-free service out of them. Certainly better than the cheap Chinese relays that were in there.

1999 CHEVROLET ASTRO VAN PROJECT
AS ALL MY CURRENT REVIEWS THIS IS ONE I CONTINUE TO LET OTHERS KNOW PARTS PURCHASED AREN'T ALWAYS A MUST IF NOT NEEDED ....BUT MY PERSONAL RULE OF THUMBS IS AS SIMPLE AS THIS I DON'T KNOW HOW THE VEHICLE WAS MAINTAINED KNOWING ITS A USED VEHICLE AND THAT ALSO INCLUDES FROM A USED DEALERSHIP NOT JUST PRIVATE SALES ....TRUST ME I WAS A REPO AGENT FOR MANY YEARS I SEEN IT MYSELF AND FELT BAD FOR THE PEOPLE THAT PURCHASED A LEMON....SO MY THEORY IS JUST THIS ....EVENTUALLY PARTS WEAR OUT ....OK WE ALL KNOW THIS ....BUT NEVER EVER WANT TO BREAK DOWN ON THE ROAD OR HIGHWAY UNEXPECTEDLY SO....MY PERSONAL TIPS ....TUNE UPS REGULARLY. REPLACING DISTRIBUTOR CAPS ROTORS COILS IF NEEDED IGNITION MODULES IF NEEDED SPARK PLUS SPARK PLUG WIRES IGNITION IGNITION IF NEEDED SENSORS AND YES RELAYS .....ELECTRICAL PARTS ARE ALWAYS MY BIGGEST ISSUES WHEN PURCHASING A USED VEHICLE ....SO I START FRESH ....SO I HAVE A PEACE OF MIND KNOWING I REPLACED THOSE PARTS CANCELLING OUT POSSIBILITIES IF I DO BREAK DOWN....NEXT BATTERY AND TERMINALS INCLUDING CABLES POSITIVE + RED AND NEGATIVE- BLACK alternators starters oil filters oil belts hoses fuel filters fuel pump coolant aka antifreeze a/c refrigerant brake fluid transmission fluids power steering fluid clutch fluid master cylinders brakes rotors drums including the hardware. Kits. Lines hoses o2sensors and so much more ....and not all at once but as time making purchases to replace parts to keep you and your family running keeping everyone safe ....so these relays are factory replacement product parts very inexpensive very affordable fitment will vary per vehicle excellent condition works great arrived quickly.....installation a breeze and glad to let everyone know I have the used 1999 Chevrolet Astro Van 4.3L V6 Running Great.....a quick note for some crank no start. Issues check the fuses relays and crank position sensors along with distributor or coils and work your way through everything with the electrical system ....once you rule that out next the fuel system and cooling system....and finally the mechanical system meaning the engine and transmission....misc.etc. And o yea security transponder key issues also Youtube has step by step videos for almost any vehicle repair...I use the myself combined with parts purchased here on amazon satisfied customer hooray

Fits vehicles other than GM.
This relay will work in vehicles other than GM. I ordered it for my 2005 RAM 1500 to replace the A/C relay. It fit and worked perfectly. This circuit has a 10 amp fuse so I know the relay is good for 10 amps and probably more. As long as your relay is a five pin with all the pin's orientation being parallel to each other, this should work. The pin layout was identical to the original relay (i.e., 85, 86, 87, 87A and 30). The only reason for 4 stars overall is I just received and installed it so I don't know the longevity yet. Otherwise it appears to be equal quality to OEM PS - Let me add my disclaimer that I'm no automotive engineer, just a DIYer trying to help others.

As Described OEM/Factory Part:Fuel Pump Relay
It Worked after first Try, Standard Factory Replacement. Works Great in Pontiac Grand Prix 2001 G.T.P. Fully Loaded:) Just a Side Bar/Note' 2 Weeks Later The 20 Year Old Fuel Pump Stopped working Due to Old AGE, Be Careful the Relay Sometimes is Start of More Trouble, Change Fuel Filter Every 3-6 Months.(Same as Oil.)
