nothing coming through vents
 

85 Cherokee. Just got a new Weber Carb on it and running. Still needs quite a bit of work but first up since it's getting cold I need heat! I can turn the fan from off to low/high and I can hear a click but nothing happens. Diagnosis?

it could be a vacumm leak somewhere, or with mine there was a plug in the back underneath my radio that was unplugged. so i plugged her in and it was just fine.:thumbsup:

Thanks ill look into these. I'm really hoping its something simple because it is really getting cold out

Also try to get a testlight and see if you are getting power to the blower motor.

x2,i see you got the weber kool. if theres no air coming out of any vents any where check electrial. if theres air coming out the defrost vents only check vacuum line

Had to take the advice! Only issue with the Weber is the air filter is a little too tall and rubs on the hood a bit. Gotta get a shorter one.

I'm not getting any air so ill start with the electrical. Thanks for the simple differentiation!
