whenever i drive the inside heats up a lot....the heat is completly off i was wondering if there is a reason for this?

mattdel

blend door and/or heater control is probably stuck/bad
or the vacuum source is pinched/off

it doesnt seem like its coming out of the vents though....more where the pedals are

Do you have longtube headers? Some one might have taken your firewall insulation out before you bought the car and now heat is coming through.

mmhmm... same thing. its all vents. the blend door decides where the heat goes.

open your windows. jk

No really what temp does your motor run at, your motor may just be running hot, does it have the stock t-stat and have you ever flushed the coolant system.

do you have an AOD...the produce a lot of heat, and will sometimes warm up the inside of the car

If your heater core has a small pin hole in it, it can release
steam into heating system even with heat turned off.

Are you getting water out of the heater core drain hole on the firewall?
or loosing coolant very slowly?
or leaking out of vents under glove box on to pasngr carpet?

all signs of bad heater core, including inside of car getting hot.

do you have a stock or catted H pipe? It could be from the cats. If your car is running rich they may be getting too hot.
