Why do my hazard lights work, but not my turn signals?
Hazard lights and turn signals use the same bulb, so it is not the bulb, the lamp, or the cables to them. Turn signals only work when the ignition is on; hazard lights work whether the ignition is on or not. The two systems have separate power supplies, so they have separate fuses. You may have a blown fuse.Different vehicles use different circuits, and it is not possible to accurately diagnose the fault with the small amount of information provided. You need a circuit diagram and a voltmeter, and a continuity tester. First locate and test the turn signal fuse. Do you have voltage to and from the turn signal switch?The hazard light switch is not a simple on/off switch. In the “on” position, a fused battery feed connects to left and right turn signal. In the “off” position, the left turn switch wire is connected to the left turn lamp and the right turn switch wire is connected to the right turn lamp, so there are 3 inputs and 2 outputs.The fault could be a fuse, turn signal switch, hazard switch, flasher unit, or a broken wire or connection.
Where is the light relay box on a 2010 Dodge Caravan?
That’s probably not the issue. You likely have a loose connection for the lightbulb inside the rear light cluster. Use an electronics contact cleaner, lightly pry up the contacts with a screwdriver, or simply tighten it.My 2005 Caravan light failed because I had water inside the light cluster. Because of that, the contacts got corroded slightly and it intermittently exhibits the same behavior and the problem is not with the device that activates those lights.The easiest way to test this would be to remove both rear light clusters and swap them.I looked at the relay diagram for your car, and I don’t think relays control turn signals in that model year.General InfoThe Ram truck has been designed and developed using standard incandescent lights. These lights are controlled by a computerized module called the “Central Body Controller” (CBC). This module controls the left front, right front, left rear and right rear lighting independently. The CBC utilizes “smart” technology that has the ability to monitor the current (amperage) on some of the lighting outputs. These monitored outputs include the headlamps, turn lamps, stop lamps and reverse lamps. The module is able to detect both electrical short and open circuit conditions. In the case of the turn lamp circuits, if the module detects too low of current then the module will assume an open circuit condition (burned out bulb) and the blinker will flash at a double flash rate.Source: http://www.rambodybuilder.com/20...Relays are used for very high amperage circuits like headlamps, starter, and fuel pump. Recently manufactured vehicles now use computer modules instead of individual relays for turn signals. This is true for Dodge Caravan since at least 1999. My 2005 Caravan uses a body control module and so does your 2010.Here’s a wiring diagram for your car, by the way. It’s valid for 2008–2016 with some minor differences. http://s3cf792cad773e861.jimcont...
Why do you have to change a car's alternator when changing the battery?
Well, three possibilities here.One. You alternator failed, killing the battery. Replace the battery, test the alternator. You can't test an alternator with a failed battery. Start the car with the new battery, voltage should go up from 12.5ish to 13–14 volt range.Rev the engine slightly (2500–3000 rpm). Turn on all the electricals, lights, air conditioning, etc. If the voltage drops below 12.8 for more than a second, look at replacing the alternator. It should spring back to 13ish.Often alternators will have a modular regulator. Most parts shops can test and determine if the alternator itself is blown, or if it's just the regulator. The brushes may be gone, and are sometimes integral to the regulator. Either way, it's cheaper than a full alternator.If the alternator is bad — doesn't make voltage; or is weak — doesn't hold voltage: then fix or replace it with the battery.Check the feed cables and battery connections on the off chance they're bad. You should do this regardless.Two. This is a low probability. Your battery failed, killing the alternator. This can happen in the case I forget a dead short in one of the cells of the battery, or a near total loss of liquid in your battery. Either way the battery case will likely be distorted, or even cracked. It will have a voltage less than 9. It may even stink of rotten eggs, with a slight taste of chewing on foil.Three. Your mechanic is a liar and a thief who's trying to get more money out of your pocket and into his. If he says that you have to replace the alternator because the battery is bad, this is the case.
Why does high coolant temperature affect the cooling of the air conditioner in a car?
The answers I've read here missed a point I'd like to add.First, modern A/C loops are not usually affected by engine coolant temp, as the AC condenser is always in front of the radiator (or possibly next to it).However, two things can affect AC performance based on the engine getting over hot.AC cutoff - in times of extreme engine cooling demand, the engine can cut off the AC compressor to save that heat load on the radiator. A brand new vehicle will usually be designed so that never ever happens, but a few years of wear and tear on all the cooling components can reduce their effectiveness and make this happen.Other Thermal loads. If an oil cooler or charge air cooler is in front of the condenser, their increased load could reduce AC performance.As everyone has said, typically engine cooling is difficult at speeds that provide plenty of air for the condenser. And typically idle, which is difficult for the condenser, is nothing for the engine cooling circuit.If your AC is cutting out during a strenuous drive, my guess is your condenser or radiator is fouled/corroded enough to reduce its performance enough to kick in the cutoff feature.
Will a car run with a bad alternator?
Yes. But it will be only running for a short time as it is running strictly off of the energy stored in the battery. Depending on what you are driving is how long it will run like that. Older vehicles will run for quite a while, if you don’t use your brakes much (because the brake lights use power), and keep the headlights off, as well as any other accys that use power. Newer vehicles will not run as long because the computer (ECU) and all of the other things that take power to monitor and regulate your engine.This isn’t recommended in any case because running a vehicle on diminishing electrical power can cause many components necessary for it to run to fail. Even in an older vehicle the coil, or condenser can be ruined. However, sometimes we have to do what we have to do in order to get out of a situation. If there is any possible way to not operate your vehicle when the alternator is bad, go that route.Good luck.
What are reasons your steering wheel won't lock?
I assume that you are referring to your steering wheel not locking in position after you stop the vehicle and take out the key?There are several possible reasons for this.1. The cog that fits into the detent on the steering column is broken and needs to be replaced.2. The detent on the steering column is worn or broken3. You have not turned the wheel far enough for the cog to find a detent. Pull the wheel first to the left, and then to the right to find the spot.4. The actuator from the solenoid to the cog is broken.To repair this will require the cover on the steering column to be removed, and probably need to have the steering wheel removed as well. Take it to a qualified shop or dealer for this. Incorrect actions could result in damage to the parts, or even the deployment of the air bag on the steering wheel. The exact disassembly required will differ for each manufacturer and possible model of vehicle. If you have a Chilton's manual for your vehicle, you can look up the repair to see what is involve.
Is it safe to drive a vehicle without power steering fluid?
No it’s not. While you CAN drive without it, the potential failure could result in stranding you on the side of the road. Anything built in the last 15 years most likely has a serpentine belt system that powers all your accessories.When you run out of power steering fluid, the bearings in your power steering pump no longer have lubrication available to keep them cool. Those bearings will fail, the pump will seize and that will result in your serpentine belt to fight against one accessory that is no longer moving. The belt will fly off the engine and all other accessories, water pump, A/C, alternator etc will be powerless and your vehicle will shortly cease to run from overheating or dead battery.
