Well, the first thing I'd normally say is to just move the lever back to the middle, but I've got a feeling you've already tried that, right?
Truth is, a problem like this is tough to pinpoint without a little more details. To really figure out what's going on with your Grand Cherokee, I'd need to ask: Is the indicator light on the dash staying on solid, or is it still flashing? Is it happening on just one side? Did it start happening out of the blue, or after some other work was done? Does it only happen when it srains? Only in the morning?
Answering those questions helps narrow it down, but based on my experience, the problem is usually one of these culprits:
- Faulty Turn Signal Switch: Nine times out of ten, the issue is the turn signal switch itself (it's often part of a "multifunction switch" that also controls your wipers and high beams). It’s located in the steering column, and over thousands of clicks, the internal contacts can wear out or get gummed up, failing to break the circuit when you cancel the signal.
- Bad Flasher Relay: Another common suspect is the flasher relay. This is the little cube that actually creates the "blink... blink... blink" you hear and see. If the relay fails internally in the 'on' position, it will send continuous power to the bulb, causing it to stay lit solid.
- Wiring Short: This one is a bit less common but definitely happens. You could have a short circuit somewhere in the wiring harness where the turn signal wire is accidentally touching another power source, keeping it lit up.
Now, the good news is you can absolutely fix this yourself. Throwing parts at it can get expensive, which is why having the right guide is key. The easiest way to save a ton on repair costs is to grab a wrench and do it from your own garage.
The repair manual for your Cherokee will have the exact troubleshooting procedures to confirm which of these parts has failed. It provides detailed, step-by-step instructions for replacing the multifunction switch (which is critical for doing it safely around the airbag) and will have wiring diagrams to trace the entire circuit from the switch to the bulb. It's everything you need to find the problem and fix it right the first time.
