Hoping someone can help me out. I am trying to fine a used battery pack for my 2007 HCH. I have tried searching the internet and the only used battery I can find is for older vehicles, or new packs which I don't want to pay the money for. I plan on reconditioning the used unit and then install it in my car and then recondition mine for a spare. It takes a month to follow the procedure posted here http://www.homepower.com/articles/rebuilding-hybrid-vehicle-battery-pack I don't want to put my car out of service for a month since it is my ride to work, that is why I want to buy a used pack. On a different note, when I use the A/C the car shudders and the RPMs jump from 1,600 to 3,000 and back and forth. I checked the car while parked and when the RPMs go to 3K the compressor engages and the cooling fans come on, when it drops back down both go off. The car was recently repaired after another car ran a red light and hit my car while my wife, daughter and 3 grandchildren were going shopping The A/C condenser had to be replaced along with the radiator, plus the body repair. We also have a noise that sounds a bit like the CV joint on the opposite side from the collision. It only happens while accelerating or the cruise is on, when my foot is off the accelerator there is no noise. Thank you anyone who has any thoughts about this post.
