Dam just had the work up on replacing the heater core on the blazer and it will run $900.00+. Everything needs to be broken down to get to it, even the seats need to be taken out! Over 9 hours labor and $88.00 for a new core. That and it still has a bunch of smaller stuff that needs fixed on the inside like the door skin coming lose on the driver`s side, the vanity mirror cover hinges, the lighter has no power, struts on the back window and a noisy rattle inside in the back somewhere. It`s a very good looking and running rig but dam that`s going to cost me to get it in great shape! I also want to see about having a performance chip, heavy brush guard and wench put on it. Also better stereo system and satellite radio and maybe a GPS map after market devise because no body carries maps anymore! Spent 5+ hours in the LA area going from gas station to gas station asking directions and looking for a paper map! Hell couldn`t even find anyone who knew the name of the street there gas station was on !!!
