Mold has taken over an NYPD fleet-services facility in Manhattan, resulting in the junking of more than a dozen infested department vehicles, law enforcement sources told The Post.

A slew of cars parked in the basement of NYPD Service Station 9 — located at 669 W. 158th St. under an overpass for Riverside Drive West — were found growing musty-smelling mold in ­August, sources said.

The police cars were so badly damaged from the mold that 14 of them were ordered condemned on Aug. 9, a source said.

“There was mold growing inside the car all over the seat, steering wheel and armrest,” another source said. “It looked like a science project.”

New exhaust fans were put in the basement — where repairs are done to department cars — and the NYPD stopped storing vehicles down there, according to sources.

A car inadvertently was left in the basement on Wednesday and by Thursday it had grown mold.

The NYPD facility, which services all vehicles for Manhattan North, was a garage for the city’s Department of Transportation from 2006 to 2012.

“These cars were condemned before any mold issues,” NYPD spokesman J. Peter Donald said.

“If a police officer was given a car with mold it in, that is unacceptable. It is not how this Department operates and falls well below the standard we strive for.”
