1994 Nissan Altima brake lights stay on

My brake lights stay on and I have to take the cable off the battery. I am having the same problem the ekim13ab wrote about on 01/05/2009. Mine is a 1994 Nissan Altima. There is no gle, gxe or se or anything else. My manual is nissan stanza altima. I did not know where fuse 18 or 23 is as suggested in ekim13ab's response. I am so aggravated with this car is cannot see straight and I cannot afford to take to a dealership. Since this seems to be a problem with more than one vehicle, nissan should repair this problem at no cost.

Please advise,
Cheryl
