(AP) — For the first time in eight months, the global shortage of computer chips won’t force General Motors to close any North American factories. The company said Friday that as of Nov. 1, all plants that had been closed on and off since February due to the shortage will be making vehicles. The shortage has forced automakers to sporadically shut down plants since late last year. That has cut supplies on dealer lots and driven new vehicle prices to record levels. But production isn’t back to normal just yet. Some of the factories will only run one shift per day. And experts say chip shortages will persist well into next year.
