forgot to say my heater on has one speed thats high how do i fix this
Replace the resistor block attached to the blower motor.
The problem could be with the blower motor resistor pack or the high speed blower relay.
The relay is what directs the voltage thru the resistor pack for all the low fan speeds or directs the voltage directly to the blower motor for the high speed. Determine which component is causing the problem. Because it could come down to $50.00-$60.00 for the resistor pack or $12.00 for the relay. And it’s a real bummer to replace a $60.00 part only to find out it was caused from a $12.00 part.

i went all over the internet asking what it could be and all say resistor ill try that first thanks
