every day i turn on 05 ls and the service parking brake comes on, the parking brake has not worked since day one that i bought it in december. so i push reset and its gone poof. but today it started to glitch out. my PB worked. push down brake engaged, foot on brake, pull up disengaged. thought it was wierd that it started to work out of nowhere but whatever. waited for wife in the parking brake light would come on then the "push foot brake" would come on then "service park brake". then my park brake was stuck on. no idea what to do. ive read that it might be dccv or weak battery. i used my A/C for the first time today due to nice weather finally and i dont know maybe that had something to do with it? please any suggestions would be great. thanks
