Perfect Replacement

I drive a 99 Jeep Grand Cherokee, and this part is hard as hell to get to. but other than that the part itself is a perfect replacement.

The original fan relay failed on my wifes 98 Chrysler Town & Country minivan at 225k miles & 14 yrs. I bought a BWD replacement relay at my local Advance store and installed it. It worked fine for 8 days then it failed. The radiator fans stopped coming on again. I took it back to the store and they promply replaced it. The 2nd relay failed after 3 days, this one would turn the fans on randomly, sometimes after parking the van overnight, the fans would be running the next morning. I took that one back and got a third one. It lasted 11 days then failed to turn the fans on again. I gave up, got my money back. I went to the local pull-apart yard and got a used Chrysler one for $3.00. It has been working correctly for the last 7 months.

Comments about CARQUEST by BWD Coolant Fan Relay:

In describing "difficult to install", it is not the fault of Advance or the part. The location is hard to get to and due to the car type. At this point, the part hasn't' been subjected to the elements for a test

      Comments about CARQUEST by BWD Coolant Fan Relay:

      Replacing this relay was just what was needed for a fixing a fan motor that ran continuously until the battery would die, even with the ignition turned off.

      I read some complaints that it's hard to get to. Just remove the air cleaner assembly! This is in no way a criticism of this part.

      Be sure to smear some dielectric grease on the underside of the part to provide proper heat transfer to the frame rail and you'll be fine.

      Made in USA! A+++++++

            I watched a Youtube video showing how to modify/cut the headlight socket/bucket (where the controller is located underneath) to aid in the installation. Pull the headlight, cut an access hole, remove 2 screws, unplug controller, install new controller, attach 2 screws, tape plastic piece you cut out for access) back into place, re-install headlight. Test run engine, monitor fan operation. It worked for me!

            Difficult to install due to location. Plug and play installation once at location. For future access, consider cutting hole in panel below headlamp assembly. I was having a code P1491 which is the fan relay. The ECU was working properly but the fan would not turn on. I found out in the process of installing that my niece's friend had wrecked the vehicle causing damage to the area where the relay was located. I asked how long they had the light on and of course it was right after the accident. No problems though ... part still working well.

            Just 2 screws to install, but the location is terrible! Use a light! I installed it first after I had removed the cooling fans assembly (one fan was wearing out) & this gave me more room to complete the installation without removing the headlight. Then I installed the cooling sensor. Everything's working! Tah-dah! 1999 Town/Country

                      Hi Roger, glad to assist you! The cooling fan motor relay is mounted in the air intake passage just below the drivers side headlight assembly. For help with your project, I recommend purchasing a Haynes or Chilton repair manual specifically for your vehicle. This should be able to assist you further into detail on how to repair or replace specific parts.

Doesn't look like what is in the Advance auto pictures but then what Advance seems to offer is the relay plus a pigtail and some wire splices. Help?

                      This BWD Relay (Part No. R4736) is the exact fit for your 2003 Jeep Grand Cherokee Laredo with 4.0L. Please check the ground wire from the PCM. If you don't get ground when the temp rises above 210, check to see if there's a ground on that wire right at the PCM. If there is, you have got a break in the wire between the PCM and the relay. If not, you have either got a bad connection from the temperature sensor or a bad PCM. For any further assistance please feel free to call 1-877-238-2623 and one of our representatives will gladly assist you with any questions or concerns you may have.

                      The radiator fan relay on your Jeep Gand Cherokee should be located behind the left front headlight. The Pulse Width Modulated (PWM) cooling fan relay is located below the right headlamp behind the bumper fascia. Remove front bumper and grill assembly. Remove 1 support bolt near front of reservoir. Remove 2 reservoir mounting bolts. Remove reservoir from vehicle to gain access to vacuum hose. Disconnect vacuum hose from reservoir fitting at rear of reservoir. Disconnect electrical connector at relay. Remove 2 relay mounting bolts and remove relay. For installing, position the relay to body and install 2 bolts. Tighten bolts to 3 N.m (25 in. lbs.) torque. Connect electrical connector to relay. Connect vacuum hose to reservoir. Install reservoir and tighten 2 bolts to 3 N.m (25 in. lbs.) torque. Install front bumper and grill assembly. The only other way to do it is to remove the right headlamp assembly and cut out a section of the hard black plastic directly under the area that the headlamp assembly would sit. Now you can see the relay. Remove the bolts holding the relay in place pull it up through the hole you just made and disconnect it from the wire harness. Install new relay.

                      This is how the dealership replaced it on my 2003 Laredo to the tune of 300 bucks the first time. When it went out again, I found a video on YouTube that showed how to replace it for 50 dollars. When I took the front right headlight out, there was a nice hole cut in the plastic right above the relay. Saved me a little time by not having to cut it myself, but mad as hell that they told me they had to remove the front bumper to get to it!

                      The code P1491 is for the cooling fan relay control circuit. Start by checking the fuse for the fan relay. It is in the box under the hood, a 40 amp fuse. This BWD Relay with part# R4736 fits your 2001 Jeep Grand Cherokee and it should be located behind passenger side headlamp.

                    I have a 2002 Jeep Cherokee Grand. I am wondering if I need a relay or relay switch. I am told these are 2 different parts even though when I research these parts, the names are used interchangeably. My fan motor does not cut off when the car is turned off unless the relay is pulled from the relay compartment on top and then it does not work at all of course. Which do I need? Thanks for the help!

                      The radiator fan control relay should be the problem. However, I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.

                      I believe there are a couple relays that are the same, swap relays to narrow down the problem. Make sure you mark the fan relay in case it is bad. The switch allows the fan to run at two different speeds depending on the tempature the vehical is.
