Alright so I am in need of your guys help. Yesterday I was driving my grand prix with the a/c on and randomly the a/c starts to surge and the car starts running funny. Right as that happened my "low windsheild washer fluid" message came up on my DIC and my rpm's started to go between about 750 and 1000. I just kept driving cause cause I was about 30 seconds from where I was going, when I parked my car I popped the hood real quick to check if anything was noticeably wrong and couldn't see anything. When I shut my hood and started to walk away I wen't to lock my car and now realized my cars horn is very faint when it locks(haven't tried to honk when driving yet but will today). I am stumped at what could cause all this to happen at once. The only recent thing I have done to my car is I put two relays in my car for my fog and low beam lights. Any help? Thanks in advance!
