I have a 1993 Buick LeSabre, and I have had a lot of wiring problems as well. Get this, I have replace the ECM computer, the prom chip, the climate control unit itself, and much more. However, non of these solved the problem you are having with hot and cold air settings. In my case the air would come on and surge and then die out completely. As it turned out, the switches on the dash were not to blame, but some people complain about those units going out. In my case I had to trace the wiring harness from the back of the control unit to the firewall under the hood. And there I found the answer. One of the connectors inside a clip had burnt up from overheating. I went to a junk yard and got a replacement clip and cut the old one out and carefully cut one wire at a time to make sure all the colors matched up on the splices....sure enough, I got the air to blow again without the hesitation.

In a similar but worse problem, I had a wiring clip unit go at the transmission plug in.....that caused it not to shift properly.
Splicing in a new complet wiring clip there help the cure the electronic shifting problem I was having.

So, my suggestion is to check all your wiring clips on the firewall side of the wiring harness that goes to the heater blower motor 1st, before you buy a whole new climate control unit. If the look fine, try a little electronic connection spray cleaner and clip them back together. Just make sure you understand how the clips unclip or you can break them. Most have a tab you lift up and then you can pull them apart. While others are more difficult in that they have a green pull tab which has to be pulled up to release the clip so you can pull it apart....good luck and I hope it helps

SOURCE: need unlock code for 2003 buick century car radio

You will need to take the car to a dealership to have the service department unlock the radio for you. They have a special code to unlock the radio and then you are required to change the code to one that you will remember. An appointment should not be needed because this takes about 5 minutes. I do not remember the code, sorry.

Make sure that you have the ventilation tubing when replacing the battery. The car is designed to vent battery gases from beneath the car. Substituting a different type battery (without vent ports, a small hole that is located at each end of the battery ) or if you decide to use the battery without the ventilation tubing, you run the risk of an explosion. This is due to the proximity of the battery to the fuel pump, which is also located beneath the seat.Underhood batteries vent naturally into the air within the engine compartment. In your car there is a small hole in front of your battery that leads to the underside of your car.Your tubing is designed to carry the battery's vapors way and direct it out of your car through this hole.
