Hello everyone. I'm new to the forum so please forgive me if I've overlooked this as a previous topic. My 2000 GTP with dual zone climate control is blowing heat only. I don't believe it to be an A/C issue because it's had other intermittant problems with zoning which went away before they could be corrected. The fan speed seems to sync with what should be happening. (ie: when t stat turned down to low temp the fan increases as if it's trying to cool. Slows down when in heat mode as well when setpoint reached) I'm not very familiar with these type of systems, but suspect a control module? Any thoughts or ideas on where to start? Thanks
