I have a couple of different problems with my car that are not really related, so I will list them in separate paragraphs. All information about what could be wrong with them would be greatly appreciated. First of all, recently my heater is not working as good as it was. Really worried about this because I have a 2 y/o who I do not want to take out in the morning into a cold car. Air conditioner has not worked for a while but I could always roll the windows down for it in the summertime. Anyway, my heater works great after I have been driving it for a little ways. But when I go out to start my car in the morning to let it warm up, even after 15 to 30 minutes, the car is still not warm. Don't know for sure if the defroster will work good or not. This just started and have not really had to use defroster yet. But after driving for a couple of minutes (usually about 5), it warms up and works great. It gets very hot, have to actually turn it down to low. I have not noticed my car running hot any lately either. I have been told by an ac guy that I need a new core for the air conditioning problem (probably, at least I think that is what he called it). Runs freon out in a couple of months when I have it put in there. He said that he could not see any obvious leaks after putting the dye in there. Said it would cost about 500 to repair. So I have not repaired this, I just roll the windows down, but the heat is much more important. Don't know if this is related to the air conditioning or not. Also another problem, not serious at all, just curious as to what could be wrong. When I bought my car, it did not have a cd player, so they agreed to have one installed. Well, I did not like the player they had, so I bought another one. My brother in law installed the new one. He blew a fuse and replaced it and everything when installing. But ever since then, I have had a couple of problems. My car used to have the headlights stay on for a couple of minutes after you cut the car off at night and then go off automatically and now it don't anymore. My interior lights do not come on when opening the doors unless the key is on (they used to). My stereo will not hold the memory for the radio stations I program in. I have to reset them every time I start the car. Automatic locks do not work unless I have the car started (they used to a long time ago). I have had this car for 5 years now, just finished paying it off actually, and I really like it and want to keep it for a while. All of these problems seem to come from whether or not the car is started. Like I said, not really that serious but just curious as to how easy it is to fix. Thanks in advance for any help on this matter.

I needed to do some work on the brakes on my 98 mazda Millenia. Each wheel has one security lug nut but when i tried to loosen them , the weld inside the socket gave out.:madhell: So i went to autozone and the guy there said i will not be able to buy a new one. If that is true, how do i get them off to replace them?
