The left headlight of my jeep patriot does not work, and it's not the bulb or fuse. I took the car into the dealership and they said the problem was the TIPM or totally intergrated power module. The TIPM would need to be replaced and would cost me $900 for parts and labor. My question is how hard would this be to replace myself. I have some car repair experience. I would need to know where to get the part, and how to replace it? I was also wondering if a find a used part for either a patriot, compass, or caliber if that would work? I understand that after I install the TIPM I would need to have the dealership program it, I'm just looking for the least expensive way to go about this.
