97 Lumina ABS noise

[jrmcc]

Whenever I touch the brake pedal (and even on dry roads) the ABS system seems to activate judging by the clicking noise I hear. When the road is actually slippery the system works as it should do but when it is dry it is very annoying to hear this noise. However apart from the noise the brakes still work fine. In order to avoid the noise over the summer I removed the fuse and even managed to forget about the problem. However I woke up quickly on a day recently when we had freezing rain. The back end slipped constantly when I braked and I started to realize I really did appreciate ABS. I put the fuse back in and all was well again. The next day the roads were dry and in order to avoid the clicking I had to remove the fuse once again. I have had the problem looked at by my local service station and they are stumped. The local GM dealer says there are no outstanding recalls on a 97 Lumina LS. Does anyone have any ideas as to what the problem could be and how to fix it ? Thanks in advance.
