My high mileage Camry loses electrical power on occasion when attempting to start. I usually notice the problem when starting with the headlights turned on. Occasionally the electrical system will completely fail right after I start the car and switch the headlights on. On one occasion while driving, I turned the headlights off/on and the electrical system failed (while driving). All pos and neg leads from battery have been cleaned, cables and alternator replaced. Battery is 4 yrs old, yet tests good when analyzed. Usually after system fails, I disconnect neg and pos. cable from battery, wait a few minutes, reconnect and the car will start. Any ideas how to determine what the problem is?

I have a 1971 Ford LTD. The radio works fine, but when I step on the brake, the volume goes lower. When I turn the blower up to high, the volume goes lower. I am thinking it is a grounding issue, but am not sure. Any suggestions to solve this problem?

| when i turn the key on somtimes the radio,wipers and the power windows do not work, it seams like the secuity is locking them out it doesnt happen all of the time but it is getting worse, is there a relay the controls these items at the same time? the security light only comes on right before you start the vehicle and then goes out. if it does work after you start it then when you try to roll down the windows or turn on the wipers on, then it turns everything back off. | |

About 30 days ago I leased an 07 Dodge Caliber SXT Sport factory equipped with the MusicGate Power 458 watt Boston Acoustics sound system. A few days after getting the car I noticed static would drown out the right channel only (Assuming the passenger side speakers are the right channel, that is.) of the sound system for 5 to 10 minutes after the car had been operational for about 20-30 minutes. The problem occurs intermittently no matter whether the tuner or CD player is in use and eventually I found that shutting the engine off while the sound system is on and then restarting the car solves the problem. (Versus shutting the sound system off first and then starting the engine up again which does nothing.) The car is at the dealership now and they of course can't duplicate the problem. An electrical diagnostic test checked out okay and the only possibility they can come up with is that the interference is caused by my cell phone. Why then doesn't it happen every time I use the car? My thought is it could be moisture related and it's been getting progressively colder and drier here in Chicago over the past 9 days so I have not had the static since Saturday Jan. 20th. I will have to wait and see if this occurs again but wondered in the interim: Has anyone else experienced this kind of problem? Heard of it? Could it really be cell phone related?? Any ideas would be most appreciated. Caerann |

This is a weird one. Took a trip last weekend in my 93 Chevy full-size (G20) conversion van with 5 other happy skiers. First problem noticed was that the transmission downshifted when the headlights were switched to high beam. After this happened a couple of times we just left the brights off. Next evening, switching on the dome lights would kill all power - engine dies, radio resets, everything! No fuse blew, and when ignition was switched off for a few seconds you could start back up - strong battery, charging ok. So, checked battery connections (OK) and left dome lights off. Day after that, coming home, stopped for gas. Switching on headlights now killed all power. Further investigation found that switching on dome light, parking light, and horn would all cause this failure. Other things were ok (brake lights, turn signals, heater fan). Tryed removing fuses, but couldn't find a combo that would leave me with headlamps - finally came home with 4-way flashers on in the dark. So, what the heck could cause this?!? No fuse is blowing (that I can find), and everything resets once the ignition is switched off. Right now I don't know what to look for and suspect that the whole thing could die permanently at any time. Help!!! KJ
