front drivers side regulator is easy to change- but costs a lot for a regulator assembly, already done it with 70,000 on 2014, but after 106,000 it failed again. Shoot this gm door regulator engineer. must have designed it on a Friday. Way too much monkey motion going on, I've replaced many door regulators over the years of various cars and this chevy volt drivers side is the WORST. At a cost of about $118- for the assembly, I decided to buy the cable kit as the motor is good, cables got jammed up $20 for kit. kit comes with no directions and a email to seller suggests watch YouTube. Videos are not good for cable placement. after 2 hours watching videos, decided to send kit back.With window taped up, back to looking for a cheaper way, but of course, Chinese haven't made a knock off on a volt- there wasn't enough made to copy.
