my heater and ac works sometimes and sometimes it doesnt. when it doesnt work it doesnt work at all. when it does work it works on all speeds. could this be a resister or relay switch? i have checked all fuses.

I'm thinking resistor. Fairly common on these. Inspect the resistor and its wiring connector for burned/melted wires, etc.
Could be either resistor or switch. Look at both or use a test light to check the circuit. If you would like us to look at it just call me and schedule an appointment (313-562-7022). I am sure we can figure it out for you.
