Question about 1999 Hyundai Sonata

1 Answer

Battery-alternator I've had years of 'electrical' problems on my 99 Hyundai Sonata GLS. 4 batteries, alternator is about 18 mo, some parts replaced because they installed battery wrong and it leaked onto some other parts. I know this sounds vague, but I don't know anything about whats under the hood. Now I need to replace the battery again, it seems to be near dead and I have no radio. If I jump it, it runs good and I can restart it within 1/2 hr. Any suggestions? The body is good and other than this, its a good car. thanks

No picture to show you, but it's on the right hand side in the engine bay either near the power steering pump reseviore or near the firewall (or somewere inbetween). Anyway, chargine the AC system is done at the "HIGH" side port (not the low side). I assume when you say 'fill' the unit, you're talking about "Charging the System with Refrigerant'?

SOURCE: How do you change the cabin air filter in a 2009 Hyundai Sonata?

I just did this on our 2007 Sonata. 1. open the glove box. On both sides of the glove box, there is a black tab which prevents the glove box from opening to far. The Chilton manual says to remove these, but that is more difficult then simply pressing inward on the sides of the glove box to release them from the channel. Now the glove box should open even more. Next, remove the piston arm from the right side of the glove box. You can do this by removing the panel on the side of the dash, but you first need to open the passenger door. You can also just use a screwdriver or other tool to slip the piston of without removing the dash side panel. Now with the glove box hanging fully open, you can see the cabin filter box. There are tabs on both sides of the front that you simply press together in order to slide the filter out of the box. This whole process from beginning to end should only take about 10 minutes and is very simple.

Battery is weak. Most auto parts stores can perform a battery diagnostic for free and even charge it if it is just weak. Take the battery out of the car and take it to tour nearest at parts store.

Engine wont turn over

Having had this problem (a couple of times on our 2002 Hyundai Sonata GLS V6) my first guess is, its probably the starter. So although there are other possibilities, I would be surprised if it's not. The first time I replaced it with a used starter from a salvage store. That turned out to be a mistake because I had to replace that one within a year. Replacing the starter isn't too hard, depending on your mechanical skill level. The quick sequence is; disconnect the battery. Remove electrical connections from starter. Remove mounting bolts (3 I think). Maneuver the starter down and out (this is a little tricky). If you choose to do this and need more detailed info let me know. I would also suggest you get one that carries a limited lifetime warranty because our Sonata may actually be on its fourth starter (I'd have to look at the records). Good luck.

99 hyundai sonata brake light and battery light is on

I would recommend you take it to a shop and have the alternator tested, or take the part off the car and have it bench tested in a store.
You may also have a bad fuse or fusable link between the battery and the alt.

Battery tested no good, replaced it, next day battery wont start car, noticed blown fuse at postive terminal, replaced it, jump started car, working fine ...... Question, will that fuse prevent battery...

the fuse must be 'intact' for electrical system to operate properly.batteries are rated in months as far as longevity is concerned,36 mo. 60 mo. etc. if you have or have access to a volt meter,battery voltage should be 12 volts with engine off,13 to 15 volts w/ engine running indicates alternator is working.

Alot of systems dont have a battery listed for 2001 hyundai sonotas so they will give you what "fits". These can touch metal parts of the car and ground the battery to the car. It will act like alternator problem and eventually kill the alternator because its overworked. I had this problem. Walmart and Advance gave me wrong batteries. I didnt know until I took it to the dealer.
