David Andrew Corcoran, of Conway Drive, Fulwood, Preston, was unanimously cleared of the charge by the jury, following a trial at Preston Crown Court.
The 30-year-old had been charged after a report was made to police two months after the alleged incident.
The complainant can not be identified for legal reasons.
Corcoran has pleaded guilty to a charge of criminal damage in relation to the woman’s car on July 21 last year.
He has since been fined £1.
