Hyundai 99 surging lights,revs and fan intermittedly
hi, I have a Hyundayi Excel 1999 model, Manual I bought from new.
Last year in october the car shook violently and then died after the engine light was coming on intermittedly. So my mobile mechanic tested it said I needed a new Alternator so He put a reconditioned one in. Car went fine until April 2008 then the car wouldn’t start and I had to pump the accelerator for a few minutes and then wait 5 to 10 minutes then it would start.INTERMITTEDLY. The moblie mechanic tested it the computer said no fault as it always restarted eventually. So I continued to drive it and it was still doing it intermittedly. It felt also like I had to keep revving the accelerator to stop it from stalling. Finally I rang Hyundai and booked it in for a check up but the day before it was to go in. The car died while I was slowing to stop at the lights. The mobile mechanic came to my rescue and narrowed it down to a black lead not sure what it was called. Then I drove it and It kept revving up and bunny hopping. So I took it to Hyundai as the mechanic suggested an auto electrician. Hyundai replaced another lead. Car seemed to go fine. Thought I was imaging the dashlights lighting up more than usual on occasion. THEN.............................. NOW my problem is that now when I drive to work at 5am in the morning my car is surging power and My front control panel and my headlights high beam. And i have noticed also my fan is surging to the next level of flow. Also It revs up a few seconds after I start it . All of this is intermittedly and so I took it back to Hyundai and they said they cant find any problem but suggested I take it back to my mobile mechanic and test the alternator.So my question is, Can anyone tell me what is my cars problem it is costing me a fortune. :( Regards Deborah -- Posted at author's request, using moderated http://www.AutoBoardz.com interface Thread archive: http://www.AutoBoardz.com/Hyundai-99...ict250188.html |

Your lucky it hasn't burned out the ECM. -- |
Re: Hyundai 99 surging lights,revs and fan intermittedly
Ditto Michael. If you're experiencing lights dimming and brightenting and
the heater fan speeding up and slowing down (and the engine isn't running significantly below idle), your alternator is faulty (or has a poor connection). If it puts out too high a charging voltage, it can kill every electronic component in the vehicle. Typical deaths are transmission and engine computers, time and alarm control modules, air flow sensors, and bulbs. I've seen overcharging alternators cause over $3000US in damage. -- Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai/ More information at http://www.talkaboutautos.com/faq.html |
