Jolly,
Thanks for the reply. I have the under the dash unit. The hoses seem to be in good working order. Before the winter, I flushed the radiator and cleaned out most of the mess there, but I didn't think to look at the heater core. Is this a relatively easy process or should I take it in and have it looked at? I can tear anything apart, it's putting it back together....correctly that gives me the most problems.
Thanks.
