My daughter has 2007 Compass Sport 2.0. it has been fairly trouble free. Recently it had a left low beam headlight out. She changed it out, but did not correct the problem and the light occasionally came on and worked. The low beam is out permanently now but everything else works fine. It has the OEM bulbs. A local mechanic said the wiring is all testing good and he thought it was the TIPM. Does this seem possible? Before buying a very expensive part I want to be sure. Also if necessary, is there a best price vendor for the part?
