Today ,id start changing transformer,nothing happen, just blower turns, but noy heating or air conditioning, I'm very frustrading,and then id change relay, and still the same, the only last thing leftis the secuencer, but after half day trying ,igive up

I don`t blame you,, I think

Sequencer is a clue, you must have an electric furnace (air handler) it is possible to have a burnt out strip heat or in line fusible link (fuse) this would be in the heat strips. This type of problem can be fixed in the matter as you started by replacing parts, sooner or later you might replace the bad part, this could get expensive, tracing the problem with a volt meter is the correct way, good luck. Mike

Truth be told,, the only thing left is not the sequencer. There are many things left. If you are indeed working on an electric furnace, I suggest you call in a pro. You are messing with high voltage, very dangerous.

Ps. Just a thought, maybe you should work on your spelling, or use spellcheck.
