the controls that regulate where the heat comes out into inside of car ( vent, defrost, floor..) does not lite or work heat onle blows to floor, can not change? any help would be appreciated
Looking for a few ideas on where to go here.
Car starts and runs fine, then it dies and battery is dead after 15 minutes.
Battery is new and load tested good at 2 different shops.
Alternator is replaced and new, both alternators load tested good at 2 different shops.
Battery voltage is 12.4V while running, as I turn on lights and A/C it drops to 11.84V.
Battery voltage then continues to drop while running, 11.83V, 11.36V, 10.98V and gets around 10V and car dies.
I do not have the 14.5 volts from the alternator on the battery while running which I think the alternator puts out to charge the battery.
So I guess what controls the alternator charging? What tells it to turn on and off?
I have no codes so am stumped.
All fuses and relays check out good. Replaced battery terminals. Wires look good.
Also battery does not drain or loose voltage while sitting.
Thanks for any help, this was my welcome home present after heart surgery. "Honey the car died lol".
I changed the battery on my car now all the lights flash and it won't start I believe it's the anti theft kicking in but I don't have a key fob is there any way to rest the ecu manually to hopefully fix this problem?
The 2009 Hyundai Sonata GLS (2.4L I-4 engine) has been intermittently starting over the past month. The battery has a full charge and the terminals are clean. When I try to start the vehicle, 1 of 3 scenarios occurs. (1) Car makes short series (about a second) of light sounding clicks, sounding like the starter is not engaging. (2) Car's starter tries to turnover the engine (via engagement of the flywheel for only an instant), then nothing. (3) Car's starter is able to turnover the engine in an instant. No scenarios demonstrate that the starter will stay engaged with the flywheel for more than an instant (if at all). Any help would be a real blessing as my family is down to one operable vehicle.
Check engine light on and car jerks while on drive or reverse
While driving rpm will jump up on there own does not change my speed they just jump up and thAn go down speed stays the same and twice my car acted like it did not want to start like if it had no gas?
My car rpms will jump up while I'm driving. Does not go any faster stays the same speed I'm driving. Also a new symptom it happened twice after shutting it off. Acted like it did not want to start, like it was not getting gas; though, I was pushing on the peddle it seemed like it had no gas to it. It will usually start right up with out using my pedal I just turn my key. but this time it did not to start, so I pumped it a few times waited about ten minute and it started right up no engine light took it to tranny dealer he said he could not figure out what was wrong with it by his computer machine he said if and when it has new symptom bring it back. well the new symptom is it not wanting to just start up. any ideas and the rpm thing is still happening.
The car was running rough and engine light came on, someone told me that my two cylinders were bad. He made the light turn off and the car wasn't running rough, but now I started my engine light is back on wondering if I can still drive the car to go to work. What can happen?? Please advise
