Works as a 2004 Jeep Grand Cherokee WJ Cooling Fan Relay
I used these to replace the cooling fan relays in a 2004 Jeep Grand Cherokee Laredo WJ. When you go looking for the cooling fan relay for the 2004 Grand Cherokee everything will point you to a different part that is located under the passenger side headlight. At least for mine this was not the case and there are two relays (high and low) located in the fuse box on the passenger side of the engine compartment. These replaced Tyco relays numbered 04848879AA 72472M after I found a blurb online that the originals were superseded with this part number so I thought I would give them a try . These are slightly smaller overall than the originals but the connectors lined up perfectly with the factory wiring connectors. They seem to work great and the cooling fan has been running fine with no overheating issues for several weeks now. Note there are 2 to a pack. I didn't see that anywhere in the posting so I ordered two. I ended up with two sets of two (and returned one set). This was actually a pleasant surprise, as I thought they seemed a little pricey when I first ordered.

Great item with a full wiring loom
Ordered it for my 1998 Jeep XJ for the cooling fan part number 56006709. MOPAR registered it as a replacement for that part number. It arrived fast with a full wiring loom and housing (which I didn't use) and it is a direct replacement for the relay in my relay box. Although it is marked made in China i hope it is a Mopar quality item.

Mopar 4727370AA Starter Relay
Works in my 2013 Jeep Grand Cherokee Trailhawk even though it wasn't the fix for my issue. The factory relay and this relay both say Made In China so no difference, most parts nowadays are made in China anyways. I'm not overly sure if this really is a genuine Mopar relay as it comes in a sealed plastic bag with no labeling on it, so 4 stars for that reason, but it does work. It was also about $12 cheaper than AutoZone's relay.
