: heater core bypass

Does anyone have any ideas on how to bypass the heater core? My blower motor doesn't work and I figured it would be easier to just bypass the heater core rather than trying to fix the motor. I drive the car in warm weather only anyway. Do I just cap the intake manifold port? what do I do with the outlet from the water pump?
thanks,
Greg

You can plug both with screw in plugs that replace the current fittings. You can also route a length of heater hose from one fitting to the other. If your core doesn't leak I would leave the hoses attached and not worry about it personally. Even without a fan you can slid the switchs to heat and defrost and it will be better than no defroster at all!!

I think I'll try to solve the heater blower motor issue rather than bypassing it. Does anyone have any trouble shooting tips for figuring out why the fan won't run? Are there any common problems with the switches that I can look at? I'd hate to have to pull the blower motor if I don't have to.
thanks,

Try running a wire from the + battery terminal direct to the terminal beside the motor, if it runs its not the motor but between the motor and switch.
