pull it and switch it with your wiper relay or a similar same part numbered one.
Remove the freon from the 91 Buick Regal with a reclaim machine. Remove the compressor belts and disconnect the lines. Unbolt and remove the compressor. Bolt in the new compressor, and connect the lines. Put the belt back on. Pull a system wide vacuum, then fill with new freon.
