I just bought my 89 corvette and noticed the lptws light on. I did put the proper air in all the tires and disconnected the battery for 10 minutes thinking i would reset the switch.But still comes on and off at times. Any Ideas? Thank-you

This is the only info I can find on the LPTWSIt's not for your year, but will give you some anfo as to how it works.

Thank-you for response. Doesn't stay on goes on and off. I found out very sensitive to alot of things and very expensive to replace.
