Also, an a/c unit is designed to last 25 to 30 years depending on the location of the outside unit.

How to connect a six wire blower motor to a four wire blower motor.
It is not possible to directly connect a six wire blower motor to a four wire blower motor because they have different wiring configurations. However, you may be able to modify the wiring to make it work, but this would require a thorough understanding of electrical circuits and potentially void the warranty of the blower motor.
If you are not familiar with electrical systems and wiring, it is recommended to consult a professional electrician or HVAC technician to ensure safe and proper installation. They will have the necessary knowledge and expertise to assess the situation and provide suitable solutions.
Carrier package unit has constant 24 volts going to fan relay, even when the thermostat is off. Is this a bad control board?
I would suggest first removing all thermostat wires from their terminals on the control board. Does fan relay coil de-energize?
If not, likely control board problem. Look for stray metal small pieces of wire or screws lodged on or beneath control board before totally condemning it. If the fan relay coil does de-energize, start narrowing issue down by connecting thermostat wires one at a time starting with 24v Red, then 24v Common if present (Brn? ), then Cooling Yellow, Then Fan Green and then Heat White. It could possibly be a short in the thermostat wire.
