I just had a thought. The way these are connected together, if one leaks, then in effect, they both leak since they are connected together before being connected at the manifold.

Is the one behind the glovebox replacable without pulling the dash? If so and IF I were VERY LUCKY, that might be the only one that is leaking and replacing it would make it operational again. Keeping me from having to do this job in the heat. It's something I would much rather do in October than July or August in Texas.

Thanks for your responses,
