Until I can fix my blend door I want to bypass the heater. Can I just put a shut-off valve on the heater hose coming off the water pump?

 

i would think it would be easier to just get a small length of hose and connect the in and out of the normal core line on the engine...loop one right into the other.

 

or what i did is used a dual ****** fitting thats pvc and some pipe clamps cost 2 bucks

 

Just fixed my blend door today. Took out the control module, took it apart and the big gear was broken. Glued it back together with 5 min epoxy, put it all back together and was able to see it move when the ac was turned on. Hopefully this repair will last a while.
