Hi All

I have a 1997 Dodge Ram Van 2500, but a conversion shorty.

My problem is that a while ago we had our radiator replaced due to it cracking when it overheated. Ever since this time our A/C works, but only when we have it on the high setting. If we leave it on the vent it will flow through cold, but it won't push the air unless on high. When set on low or medium, just the natural air flow comes through, nothing pushing it.

We just had the car get a full tune up, but neglected to mention the air issue. We have tried contact cleaner and checked fuses, all seems fine.

Can anyone help?

 

Blower fan resistor block is bad; go to dealer for a new one, about $25.
