Hyundai Tucson Relays

Not automatically. The Tucson sold in South Africa as JM, LM, TL and NX4, and the LM Tucson and the ix35 are the same vehicle sold under two names in different markets, so ix35 stock is a legitimate source for LM-generation parts and vice versa. Send us the generation code off your VIN plate and we will confirm it either way before anything is dispatched.

We work backwards from the VIN: generation first, then engine family, then whether the car is pre- or post-facelift within that generation. On the Tucson specifically, the LM Tucson and the ix35 are the same vehicle sold under two names in different markets, so ix35 stock is a legitimate source for LM-generation parts and vice versa.

Only if it is a CRDi diesel. That is the single biggest difference between the relay layout on a diesel and a petrol Hyundai — the Kappa and Gamma petrol cars have no glow plugs and therefore no glow plug relay at all. If a diesel is hard to start cold, that relay is the first place to look.

The pattern we see most is a no-start with the fuel pump silent, a loud click from the fuse box, cooling fans stuck permanently on or off, or an electrical fault that comes and goes with no obvious trigger. Intermittent is the word that most often means relay.

Not necessarily, and this is worth checking before you buy anything. A click without crank means the relay is energising but not passing enough current to the starter solenoid — and a tired battery mimics that exactly. We check battery voltage under load and the earth straps before condemning the relay.

Work off the diagram on the underside of your own fuse-box lid rather than a diagram from the internet, because air-conditioned and non-air-conditioned derivatives fit different relays and facelift cars occasionally moved a slot. To test, swap it with an identical relay of the same rating from a non-critical circuit such as the horn and see whether the fault follows.
