I can’t control the blower on the A/C, heater. It’s always on full blast. What is causing this. And will it be expensive to repair. Can I just live with it on all the time?
Runs even when switched off? It’s the switch or some control module.
Do you mean it only runs on high speed, low and medium dead?
It’s probably the resistor pack (or module etc.).
Usually near the blower motor, under the dash.
Part ~$25-50. With installation ~$50-100.
It’s a DIY job if you’re handy with screwdrivers and small wrenches.
What kind of car?
it’s a town and country Chrysler 2003 van.
Thanks for your help.
