Hoping someone might have the time to lend a hand. I've had a couple issues with my zj that I can't seem to figure out. I know there aren't many people in Pueblo but I'll be in the Springs tomorrow, late afternoon for an appointment, and so if anyone might have a little bit of spare time and could give some guidance that would be great! I have basic tools (all packed up in the back of the jeep at the moment in fact).
So the two issues I'm dealing with now both are probably so stupidly simple that they are evading me.
My horn just randomly stopped working entirely. All my relays are fine and I've even swapped relays around to see if it changed anything, but nodda. Someone suggested testing the wires but I don't actually have a continuity tester.
The other issue I'm struggling with is what sounds like a belt squeal. However, I know it's not the belt as I replaced the serp belt recently and have properly greased it. I thought it was one of the bearings in a pulley, but if it is, I can't seem to figure it out. The tensioner is brand new, as are the alternator and water pump and so I can't imagine the bearings are already going bad in those pulleys. It's odd because it doesn't always squeal, but if it does, I can pop the hood, spray WD40 on any ONE pulley, or belt conditioner on the belt and it suddenly stops. I can grease a different pulley each time, and it doesn't seem to matter which one, but the sound will almost instantly stop. It's driving me insane that I can't locate the exact cause of the squeal.
So, anyone that has time tomorrow and wouldn't mind taking a look at it with me, this girl would greatly appreciate it! (And the opportunity to meet other local Jeepers would be pretty nice too since I've only met 2 down here in Pueblo thus far)
When you are getting belt noises like that, if the tensioner and all the pulley bearings are good, then its likely oil or some other lube that has gotten onto the belt, especially if it is more of a chirp, not a steady noise. That means its in one spot. May have a little oil, or coolant on a pulley, and when you changed belts, it got onto the new one too. You shouldnt have to grease a belt, I'm not sure what you mean by you greased it. WD40 and some other penetrants will soften the rubber some, helping silence the belt, but in the long run its not the answer. Now if you have a weak belt tensioner, then its a whole different ballgame. As to the horn, could be a poor connection at the horn itself. Have seen a dodge caravan connector at the horn, where the pins in the connector itself were not holding contact with the mating pins of the horn. Caused the same complaint. Also have seen contact issues in the steering wheel itself too.
sorry, "greased" was a bad choice of words. I have used a belt conditioner on it and it still doesn't seem to help. The belt tensioner is almost brand new. I just replaced it like 2 months ago, if that. I am going to be extremely ticked off if it's bad already. As for the horn, I'll have to find some more time this upcoming weekend to see if I can check it out. I have never messed with a horn before so I have no idea what I'm doing.
I hate using belt conditioner, because it typically is a band aid fix. If you are getting a belt chirp or squeal, then you have oil or coolant on the pulleys, on your hands when you installed it, or possibly an accessory trying to lock up.
