Electronic Climate Control-No heat
Hi:
I haven't had heat in a week. My car has the electronic climate control, and the HVAC modulator (?) was replaced in November of 2007 by the previous owner, according to the paperwork given to me.
I replaced the power antenna last week and disconnected the negative battery cable before doing it. I don't know if the system needs to be reset (?) as a result. The coolant level if fine, and the unit worked without problem before replacing the antenna.
Any suggestions on what to do/or where to look?
Thanks!

Hi
It could be your air mix actuator. Do a search here for 'air mix actuator'
Yours possibly broke when you reconnected your battery cable.
The gears in the air mix actuator are prone to break over time.

Hiya Snaggle..
Pull out the glove box insert and take alook through the hole to see the actuator arm. Move the temp up and down (allowing 45 full seconds for it to move) and see if it appears as a fluid motion or not at all.
Any unsmooth opertation usually points to a air mix actuator.
Assumed your temp is blinking on the display?
