#164 of 575 Air Conditioning
Jul 06, 2006 (1:12 pm)
I have a 2003 Buick Century that has a A/C problem. This is what happens when I turn the A/C on:
1. The compressor kicks on, however, only hot air comes out. Almost like it's pulling air from the outside (like it was on Vent).
2. I put the A/C on MAX but still only hot air.
I have done some troubleshooting and this is what I've done:
1. Made sure the compress is working and it is.
2. Tried to see if it was low on freon - it wasn't.
3. Check the fuses, they were fine.
What else should I look for? Any help would be greatly appreciated.

Did you check to see if you have both of the temp selector knobs pulled down to the blue area for cold and not in the red area for hot? Just the opposite happened to me last winter when i had the selector in the blue one cold morning and liked to froze to death. Made me feel kinda silly later.

Yes, I did make sure it was in the down position (blue area). Thanks for the suggestion!

#168 of 575 1999 Buick Century wont start after engine install
Jul 10, 2006 (4:37 am)
I installed a new engine and computer in my 1999 Century and when I finsihed and went to start it, It did nothing no crank, the starter didnt even make a sound. I did notice that the security light stays on now. Is it a way to reset it because I thinks it just wont start because of security?

I also have a similar problem. Although it didn't happen "just one day", my 96 century windows do not go up easily. They usually come down fine, but will not go up easily. I have lubricated the belt and that has not helped. I don't have the tools to be able to remove the motor to check it out. The car is in good shape, and there is no rust on the door interiors. All windows exhibit similar 'behavior', but 2 windows are definitely worse off. Any thoughts on troubleshooting or correcting? Thanks.

Like Alfonzo I recently had a leaky intake manifold gasket and had to pay $700 to fix the problem. My mechanic also told me that this is a chronic problem for the last redesign (97-04) of the Century and it's 3.1 engine.
Shortly after I "fixed" the problem the engine light came on and I had difficulty starting the engine. I had to race the engine and throw it into gear. I thought this problem was similar to clogged fuel injectors. My mechanic concurred. The engine now starts fine and my mechanic thinks I may have blew the debris, which may have fallen in while he had the engine torn apart, out. He used his diagnostic brick (machine) to reset the engine light and every thing ran fine for a short while. Now the light is back on but the engine seems to be running fine. I will be taking it back in.
Does anyone know what kind of problems might trigger the engine light, especially those problems that might be a result of repairing a leaky intake manifold gasket?

I just removed the glove box on my 2000 century today while installing satellite radio. Removing the glove box was the easiest part. I removed 3 hinge screws on bottom, tilted box sideways, jiggled a little, and it popped out. I used reverse to put it back in. Installing the satellite radio was a real hoot. It helps if your arms are double jointed while working under the dash.
#172 of 575 Wiring Problems with 94 Buick Century 3.1 liter
Jul 13, 2006 (8:55 am)
I just purchased a 94 Buick Century 3.1 liter station wagon which ran well until I replaced the plugs and wires.
Now, I have the Service Engine Soon Light on and the scan has multiple error codes including the crank position sensor. Oh yes, the engine now runs poorly, sigh.
As the rear plugs and wires are hard to access and require removing the coil pack assembly and disconnecting wiring, I am suspecting that I damaged, bent, or broke a connection or wire that does not show. It looks like the previous owner added a wire to turn the AC compressor on.
I have plugged/unplugged all the connections again, checked vacuum lines, and closely examined everything over and over again. I am putting off serious troubleshooting until this weekend.
I am open to suggestions/advice on troubleshooting, bypassing the bad wires, or even replacing the somewhat shakey looking harness from a salvage yard. I am fairly experienced and skilled both but am always eager for advice or suggestions that may help.

You may want to carefully examine all the numerous vacuum connections and hoses as I have found and repaired/replaced many bad ones.
One tip is to go to your auto parts store and buy a roll of the appropriate size vacuum hose plus elbows and connectors.
If the vacuum is not it, then you may have pulled or loosened up a connection in one of the harnesses. Alas, that seems to be my problem in post 172. I figured either a lot of things went wrong simultaneously or I have a wiring harness problem.
