Blower motor won't shut off in heat mode but works fine in A/C mode

I have an older lennox unit that is pilot light. The blower motor won't shut off when the temp is reached on the thermostat but it works fine in ac mode. What could cause this? I'm confused because it worked 2 weeks ago when I turned my ac off and the thermostat is in auto and only shuts off when I turn it off at the unit itself
