Come sun, rain or snow, your Tahoe takes you anywhere with ease. This inevitable exposure the elements takes a toll on its electrical components. Over time, seals fail and wires loosen, allowing moisture to corrode your Tahoe engine control computer. When this happens, the check engine light stays on, your SUV may not start and it's time to replace the ECM.
