What could cause the heater blower to stop working even after it and the heater control was replaced on a 1992 Ford Thunderbird?
You still have a blower resister assembly, wiring, and a blower motor itself, in that system. Any one of those could have a problem. You need to use a test light at the blower motor connector and see if you are getting both power and ground. If you are missing a ground, most likely you have a bad blower resister assembly. If you are mssing power, check fuses and wiring. If you have both power and ground, and the motor isn't working, you need a blower motor. I have also found that sometimes tapping with a screwdriver handle on the motor will make it come on, and if that is the case, then again, you have a bad blower motor.
What else can I help you with?

Why does cruise control and blower motor not work until you hit the dash?
I am having similar symptoms with my 99 Buick Regal. The blower motor will run all the time even with the keys out. When the blower isn't working neither will the cruise control. I have researched it and believe it to be the ignition switch. I have not replaced it yet, but feel that is the most logical thing. It's also possible that in your situation it may be either the Blower Control Module or a relay. However, it's likely the ignition.

When you replace a blower motor do you have to replace the resistor module too?
Something called a blower control module takes the place and is found in the hole where you would find a blower resistor, so there isn't a blower resistor in that vehicle. As far as the blower control module is concerned, the module is serviced as a unit. No part can be fixed or replaced. This is not to be confused with the control head in the dash. The blower control module is held into the heater box with two 8mm screws outside the firewall under the hood, where you would normally find the blower resistor pack.

First you have to see if your blower motor is working or not. If it is and still you have no heat then your heater-core is blocked and needs to be replaced.

blower motor relay or control circuit...read up on the checks for this.. ...everyone should have a manual for their vehicle(parts store or dealer), and a local library should have professional shop manuals available in the REFERENCE section for free...make copies of the appropriate sections...read up and good luck :)
