Woody,

Your tip is was most timely. I am having problems with my heating system.

Front heater:  Blower motor runs fine on "High", but on the other settings, the
motor runs in fits and starts. Very erratic.  Is this symptom solid for a relay
problem? And you say I can get to it somehow through the dash, without having to
remove it. That would be terrific.

Rear Heater: Blower runs fine, but I have a leak. I think the valve is leaking.
Anyone with experience in changing it out. Are the valves expensive. Is it
difficult. If I tackle the task, is there anything else I deed to address while I
have it apart?

Thanks,

John Rodgers
