The blower fan for the A/C / Heater only works on high speed......99 Ram 1500

 

Try replacing your resistor. Its a small part and costs about 10-20 bucks and can be changed on your own. I cant remember where the blower fan is on your truck its either on the fire wall under the hood or under the dash. It can be identified by the plug that goes into it and the two small screws that hold it down just look for an electric motor and the resistor is right near it. This part controls fan speed.

 

resistor dude they always go out and give no high or only high works

 

thanks guys that kicked its ***!

Replace the blower resistor block. (posting in the nitro section would be a good plan too.... this forum is for second gen trucks.)
