Q: 99 Grand am SE has a squeak all the time. Belts are tight and tried belt dressing. Also when the heater is on the engine shakes.

asked by on March 17, 2018

Car squeaks all the time. Shakes very bad when the heater is on. I'm afraid the shaking will shake something loose and hurt the engine. Why would it shake so bad with the heater on? Thank you
