I am both short of time and $ right now. I believe I have spotted the two hoses that go thru the firewall to the heater core. As a temporary fix could I turn them into a loop by disconnecting one and hooking the remaining back into the engine (where they seem to come from)? I am actually getting water dripping from the under dash unit onto the floor, so need to do something quick. I'm in Southern CA, so not having a heater for a while is not a big issue.
