Get a new motherfucking battery. Are you one of those fucking idiots that needs a boost every day?

The battery is 6 weeks old. Alternator voltage regulator and belt are 4 weeks old.

Battery voltage while running is completely normal, like 13.7 volts with everything running. Totally healthy. The gauge cluster is just 35 years old and I probably have some grounding issues.

even better:
>use turn signals
>dash arrows don't light up, but EGR light flashes
>use hazards
>broken fuel gauge which is always pegged to F starts to swing the needle back and forth across the gauge in time with the lights

Should 14.something. your charging system is unhealthy.

The service manual disagrees.

You mean owning a 90's VW?

>go around a corner
>wipers turn on

Your ignition coil is probably making some weird inductive loop that resonates on some harmonic of the frequency of the transmitter. One of those anti-EFI ferrite beads on the primary wire of your coil might help. Or it could grenade your engine, I don't really know.

80's BMW. Close enough.

I'd suck some dick for a Mark-I or II GTI though...

Sounds like Y'all need to stop driving VW's.

Bad ground dummy

This is an old as balls chevy pickup, not a fuckswagon.

You drive a 2.4 ecotec g6. Mine did that sometimes the radio stays on too

>fuel gauge does it's own thing, randomly dropping and jumping.
>the "_____ miles to empty" counter still works, so just use that instead.

I'm assuming it's the driver circuitry to the fuel gauge and not the actual level sensor itself.

>When hitting rough roads, or taking fast turns with less than 1/2 tank, I can hear the gas sloshing around the tank.

There are only baffles in the top 1/2 of the tank, and only stop fore-aft sloshing, not side-to-side. Gotta love Chrysler engineering.

>drive in rain, ABS light comes on despite car not having ABS

>CEL constantly on because the gas cap sensor is faulty, as it is on LITERALLY EVERY PT Cruiser.
Chrysler never acknowledged this, and the fix is just 'ignore the CEL unless it flashes'

Nah, not the absolute worst. It's been reliable enough, it's roomy as all fuck, and it's pretty good in snow. Crap quality on non-essential bits, and some quite poor engineering compromises in some areas, but the engine and (manual) trans are fucking stout and that little 2.4 is very torquey. I've towed 3100 pounds with mine on several occasions, and it did so pretty damn well, given that it has only 150 hp.
I will say that the only way to remove the engine is a fucking pain. You need to lift the car, drop the transaxle, remove 99% of the front suspensions, then drop the engine out the bottom.

Early 2000s Chebby Aveos (actually Daewoos lol) are worse. The engines grenade at 30,000 mile intervals, it's like clockwork. 95hp+3395 pound car is a bad combo.
KDM version of the car only weighs like 2600 pounds. Fuckin' murican safety shit.

Fucking chevy aveos, Jesus Christ
My brother bought one when I still had my 1991 accord.
He got torched by a 20 year old sedan with rear drum brakes by several minutes on a 15 minute hoon

My GF is scared to take hers on the highway. It's /okay/ in suburb driving and it's better in the snow than her Town Car, which is the only reason that we keep the Aveo around.

g5, actually.

>not having a mechanical odometer
Do you even shitbox?

Having something that works perfectly has a lot of pressure. If everything is going right, something's always wrong, but you don't know what it is because to you, it looks like everything's working perfectly.

If shit's fucked up just enough, it's easier because you can look at and identify that it's a little fucked.

And if you really fuck it up, who cares? It's already fucked. Ding your door on a beat up 1992 Honda? Who gives a shit, it's already covered in peeling clear coat and rock chips. Ding your door on a 2017 Corvette? The world is fucking over.

>go over bump

>approaching an incline at an odd angle produces a audible "thunk" from the rear axle. this one is repeatable

justXJthings.jpg

I think the front noise is just the track bar catching on something since it has coil spacers in the front. not sure what the rear noise is, but one of the rear fender flares is a little loose, so that might have something to do with it.

>rolling in first

Run another ground from your battery to the car body with some heavy duty copper wire and some bots.

That is if your battery really isn't fucked.

Lol what year? My golf has been decent for 100k miles and 8 years old, except the squeaking clutch pedal, the taillight that goes out

There's your problem

07, had 180,000 on it when I sold it. was a real piece of shit but it was wheels, kinda miss her until I start counting the things that were broken or on the verge of breaking.

sprung clutch and dual mass flywheel (if newer than say mid 2000s)

My car use to do that, you must not have power stering.

I only found out about the rear brake riding at night

My Samurai had a similar problem, at idle it would rev around 2k, turning on anything, windshield wipers, fan, headlights etc would make it rev to 4k

OP this happens on almost every single modern car but normies wont notice it

the draw on the system is spec to within a a reasonable amount of amperage for popping a fuse for that corresponding component/system

so that when an actual fluctuation occurs that could damage something, the fuse blows and protects the component

its basic circuit design

Your engine idle rpm goes down if you draw more current from the alternator

>SRS light comes on while I'm driving

They still show up occasionally

this. a whine coming from the speakers is almost always a grounding issue

It's gotta be a bad ground but I don't know where to start on looking for where all the engine grounds are.


Bulb is going out. Car got overnight cold and the metal in the bulb contracted enough to work again. Replace it anyway, they're $5 and it takes 2 minutes to change it.

Hazard flasher relay is bad, replace.
Check transmission fluid level and condition. If both are good then it's probably the 1-2 shift solenoid.

This, my 98 Legacy does that. It has a regular solid flywheel and sprung clutch though.

Coolant would be white smoke, oil is blue smoke. Black smoke is unburnt fuel.

You can't flip the lock switch with the door open?

...

oh its a mix of all 3. there's a coolant leak and oil leak, and its not burning the fuel cause it misses. I would fix it, but it'd be easier to just replace the engine.

It's a Miata. Just fuck my shit up.

Adjust compressor clutch air gap
Replace heater core
Replace wipers with correct size wipers
Check alternator and wiring
Replace all bulbs and fuse, check brake lights too.
Tap the horn itself with the handle of a screwdriver a bunch while someone else holds the horn button. If that doesn't work, listen for the horn relay clicking when the horn button is pressed, if it doesn't then replace it.
