20 Most Recent 1998 Oldsmobile Achieva Questions & Answers

Ok, I have been in your situation. Locate the Coolant line from the radiator to the firewall, there are actually 2. One has a valve type device on it. Remove that device and replace it with a piece of straight pipe. Locate your AC compressor. Disconnect the Wires to the Compressor so it can not activate when you select defrost. During the Winter you want the heat and should not need the AC side or your system anyway. This should fix you up for the rest of the winter, in the spring re-install the valve and reconnect the AC. Also, make sure you plug any vacum lines taht are connected to that valve on teh radiator line.

You need to clean the P/S pump, all connections, and the hoses with a good degreaser. After everything is totally clean and dry start the engine and turn the wheel left and right a few times to increase pressure then shut it down and start looking for the leak. Look around the pump case, check at all clamps and tighten them all, check metal lines connected to the steering gear assembly. Get under the vehicle with a flashlight and look everywhere. If you can find no leaks anywhere in the system then the steering rack itself is leaking internally and will need replacing.

If you tightened the rockers too far, the valves are probably leaking.

15 amp horn fuse.

There is a couple of ways to disconnect the horn. The easiest of which is to remove the fuse in the fuse panel. The horn itself is located behind the front grill to the side or lower portion of the radiator. You could disconnect wire from it but, my suggestion would be to fix the problem. The horn is an important safety feature. How else would you alert a driver, who has failed to check their blind spot, and is moving into your lane about to collide with you? That is just one scenario but there are countless situations that may require that you use your horn and in some states it is required by law to work properly. I suggest you post a question asking why it keeps honking and how to fix it. Include details such as what you were doing when it became stuck and any related service recently preformed. Good Luck.
