I took the 94 Buick Lesabre to get the ECM changed and my car now only blows in defrost mode. Think it had to do with the work the mechanic did or if not what is the problem

He most likely either damaged or knocked off the vacuum supply hose. There is a small black plastic hose that runs from the dash controls, through the firewall to a vacuum supply near or on the engine. The line may also branch off to a plastic ball that is a vacuum resevoir for reserve, If the hose is knocked of anywhere along there or damaged with a hole it it, you'll get that symptom.
