#102 of 104 Re: Battery goes to 7.0 volts [bainms] by tmirgliotta Nov 04, 2009 (3:45 pm)
Replying to: bainms (Nov 03, 2009 8:05 am) I've had this 05 trailblazer almost a year to the day and haven't had this issue this bad untill tonight. Coming home on the highway it kept losing power and almost stalled out several times. In the past its done it a little but never this badly. Had the charging system tested and they said everything was fine. I'll try this 30 second idle thing but can you reply and let me know if you have anymore problems
#103 of 104 02 Trailblazer electrical/starter problems by lpradetto Nov 05, 2009 (11:15 am)
I have a 2002 Trailblazer that I've been having problems with the electrical system for a couple of years. At first the emergency lights would go on when the right turn signal was activated. This only happened when it was raining or very cold. Then the dome lights started flashing on and off a couple of times. Last December the battery died and we had it replaced by a local shop, asked about the lights and he checked it out and said he couldn't find a problem with anything. He replaced the battery again in March after numerous checks. We still have the problems with the lights and battery dying. In April we decided to take it back to the dealer ship we purchased it from. They say there is no drain showing on the vehicle but that GM has a couple of notices on the ignition and rear wiper motor cause battery drains, so we have them replaced. We didn't have any more problems until late September, oddly enough when the weather started to cool and get wet. Then the car would not start when the key was turned. Nothing, no clicking, lights, radio or anything. But if I tried again it would start right up. This happened about three times in the last three weeks and we had just decide to take it back in to have it checked out when it wouldn't start at all. This was last Wednesday. We jumped it and it ran fine again. We took it in to the dealership Saturday, explained that we had it in there back in April, what we had done then and what it was doing now. They called on Tuesday and said the battery had a bad cell and that would be the reason for the battery drain. When I asked if that would cause the problem with the ignition not starting at first then starting right up on the second try she said that she didn't think so, but there was nothing about the ignition problem on the work order so he might not have checked it. I asked to talk to the manager we talked to on Saturday when we took it in. I explained to him that I was told that the problem with the electrical was a bad cell in the battery. That the tech was not even told about the ignition. He said that the ignition wasn't the problem, that the battery drain was the major concern, so there was no reason to mention that. After going around with him for awhile he let slip that the battery tested fine on Saturday but that on Monday when they checked it again the bad cell showed up. According to him there is no way that the ignition or anything they did could have caused the break down in the battery. And that it would logical that it might be a problem with the ignition again causing all our problems. But that he didn't‘ want to replace it unless he could tell for sure and there was no way to check to see if it is bad. We are picking it up tomorrow. I didn't have the battery replaced. I'm going to have to take it to someone else. But I'm running out of options, we live in a very rural area and there are only so many repair shops around. Anyone have any ideas about what could cause the ignition to delay like it is and why would the battery suddenly go bad like it did? I would like to have an idea about it when I take it back in. Thanks, Linda And sorry this is so long
