Experiencing cooling fan issues with your 1999 Toyota Camry? If your engine is running hotter than usual or you’ve noticed your cooling fan isn’t kicking in, a common culprit could be a faulty cooling fan relay. Let’s investigate this potential problem and get your Camry running cool again.
The cooling fan relay on your ’99 Toyota Camry, particularly if it’s the 2.0-liter model, is typically located in the engine bay. Look towards the back left side. You’re searching for a black box with a lid. This box houses fuses and relays, and often has a diagram printed on the inside of the lid. This diagram is your key to locating the correct relay.
Inside this box, you’ll find relays responsible for various electrical functions, including your cooling fans. There are usually two relays associated with the fans: one for the primary engine cooling fan and another for the air conditioning fan. The AC fan often provides additional cooling by engaging a second fan when the air conditioning is turned on.
To diagnose a potentially bad engine cooling fan relay, you’ll need to identify the specific relay for engine cooling. Refer to the diagram on the inside of the fuse box lid to pinpoint it. If you’re unsure, a quick online search for “1999 Toyota Camry cooling fan relay location” can also provide visual aids and diagrams.
Once you’ve identified the relay, a simple test is to swap it with another relay of the same type that controls a less critical function. A common relay to temporarily borrow is the horn relay, assuming it’s the same type. Swap the relays and see if your cooling fans now operate correctly. Turning on your air conditioning should also engage the second fan, providing another test.
If swapping the relay resolves the issue and your fan starts working again, then you’ve likely found your problem – a faulty engine cooling fan relay. While this is a common issue and often the solution, it’s important to note that this is a likely diagnosis, but further electrical testing might be needed to confirm or rule out other potential problems in your ’99 Toyota Camry’s cooling system.
