Heating, Air Conditioning, Fridge, HVAC/Sequencers


I have a Lennox furnace and the fan wont come on in auto. I think its the relay sequencer because it comes on in the on position and a/c mode. I took the cover off and I can here it ticking like its trying to work but its just not coming on like the contacts are burnt up. Sometimes it will come on in auto and sometimes it wont, sometimes it ticks several times before it comes on, but regardless it will come on every time in the on position. My questions are 1) am I accurate in my assumption 2) should I just replace all of the sequencers or which sequencer is the blower sequencer I have 2 72f8301, 1 14b0501, and one 58c9701
Thank you for your time :)
