General Heater motor resistor

If you remove the heater motor speed resistor does it make you loose all the heat

I think the resistor you are talking about controls the fan speed and as such won't change the heat as this is controlled by the amount of engine coolant that goes through the heater matrix (radiator). However the fan may not work once the resistor is remove, so won't blow any of the warmed air out.
Why would you want to remove it?

Well I have no heat in my car the auto electrician has said it could be down to that or the switch that's on the dash it's self. he can get the fan blowing cold air on a switch but the wires to the switch gets to hot. The pipes that go to the heater matrix are getting hot. I'm confused n don't no what the cause of my lack of heat is

I don't mean to sound patronising but just need to make sure of this first...
You're saying it never gives out heat no matter what length of journey then?

If that's the case and you've set the temp to "MAX", maybe it's the stepper motor that lets more or less heat out from the matrix area?
Trouble is, it could be lots of different things so it'll be a case of test each thing first but starting with the obvious.
Is the coolant level ok?
Does the car reach working temp as normal? (Multiplas tend to run cool normally by the way)

The coolant is at max it has 3 bars on the digital read out i have all the switches on the fan speed on 4 on it on hot and still no heat it's been like it since I brought it. I don't have the LCD temp on the dash but the auto eletrician said all the wires are earthing

Can you feel ANY heat coming out of the dash vents?

 

[Jon mabbitt]

No none only air I get is the cold from outside lol
