Having problems with your 1997 Pontiac Bonneville ?
Heat goes in an out sometimes it doesn't come on for days but it only does it when its cold out
Replace heater blower moter. I also have a 97 bonneville and mine was doing the same thing. Pretty much it worked when it felt like it. It cost $45.00 for the motor and heat works fine now.
