Is there anything I should be aware of when bypassing the heater core on a '95 Grand Marquis? The core has started leaking a bit and I thought I would just short-circuit the hoses before they go through the firewall as a temporary fix until I have the time (looks like an all-day job) to take the dashboard off to get at the heater core. Since it's summer I'll be using the air conditioning, but I can live without heat for awhile.
