frown 1993 Taurus Climate Selector

Problem: Heater is blowing cold air. When I turn the climate selector, nothing is moving. It just turns. When I turn the mode selector from off to vent, to defrost, to floor and mix, I hear and can see all the arms on the levelers moving. Could the knob be going bad? Also, can I remove the radio to get to any of this stuff and move the blend door by hand? Help!!!!!!!!!!!!!!!

1993 Ford had already gone to an electronic actuator for the temperature blend door. No cable. Before you go digging into the dash, you need to check some things under hood. Is the coolant full in the radiator and up to the full cold or full hot line??? Is the coolant clean or brown and full of scale and rust??? Are both of the heater hoses going into the heater core hot or one hot and one slightly cooler, but still hot??? What is the temperature gauge doing, is it staying in the cold range for an excessive amount of time??? As far as accessing the actuator, removing the radio and coin/cup holders (or CD player on high series) may help. Partially remove the A/C controls (the bezel surrounding the cluster and A/C controls has to come off first) to possibly get a better look. The electronic blend door actuators are still a common issue to this day. But check out under the hood first.

Re: 1993 Taurus Climate Selector

both heater hoses are hot. Water in raditator green. Temp. gauage is moving within the limits. When I move the climate knob from left to right I do not hear anything moving. Could it be the knob itself. Does it have a elect. surge going from it to the box or is it vaccumed control? I flushed the heater core, water going through it good. I do not use the air cond anymore. If I can just get it open enough to get heat, I would be happy. It is my daughter's car that she drives to college. She needs some heat. Thanks for any info.

Let me repeat this. It is an electronic actuator (motor) on top of the box. Earlier models had a cable. The actuator is a common failure, not the knob. They've used the same actuator on several Ford models for years.

Re: 1993 Taurus Climate Selector

Can I get to this electronic actuator (motor) by taking the radio and the coin holder out? Do you know where I can find a diagram of any of this? I have been on the internet trying to find one, but cannot. Would autozone have a diagram of this? Thanks for the info.

I'll re-type this I guess.

As far as accessing the actuator, removing the radio and coin/cup holders (or CD player on high series) may help. Partially remove the A/C controls (the bezel surrounding the cluster and A/C controls has to come off first) to possibly get a better look.
