The problem is vacuum isn't getting to the controls correctly or the control is defective. Check under the hood for a small 1/8" black plastic line that leads from the engine into the car in a wiring harness. The end of the lne should be connected to a vacuum source. Often the break due to heat.

Warranty?? It shoild be depending on the in service date. 3 Years and 36K

Good luck
