you can see the little line i have circled in red in my attachment on my post. this line runs into the fender well to a vacum reservoir. this was broke on mine and was what was causing it to only comer out of the defrost. and as far as having no heat, if you lay on your driverside floor and look behind the haet/ac comtrol panel you can see a little vacum controlled module and there is a (on mine a yellow line) running into it. i will try to get yall a pic of it. but that came un-done on mine during the swap and when i hooked it back up i had heat again. let me know if i can help anymore.

In the pic you posted, Mine has all of those lines attached. One goes into the fender well, one into the firewall and one into the wrap of wires and stuff. HOWEVER I check my vac dist. block and the A/C vancum line in broken. will this cause this?



EDIT : Just looked at the diagram on your thread and THATS THE PROBLEM!! Well for the defrost anyway.

I noticed the same vacuum line disconnected on mine yesterday, but didnt know what it was for... I've been wondering why only the defroster heat works!
