Heater Not Working

[Will Eastman 6]

My heater fan descided to stop working recently, so i started faffing about testing the fan worked sing a different power source (it did) n messing about with the circuitboard thing behind the control knobs. Having no luck i did a search and found that a common fault is the resistor thing, so i took this out (it looked pretty nakered) and replaced it. But now the heater still doesnt work. What else could it be? One thing i noticed is that the resistor that i took out had 4 pins on the conector, and the one i put in had 5. Oh and my stero wont turn on or anything, dont know if this could be related (fuses look fine) thanks

You checked your heater matrix isn't leaking?

No but its not there heat thats the probleme its the fan. Would this stop the fan working?

You mentioned your radio has also stopped working, so if the matrix was leaking, it could have shorted it out.

Ahh i see, how can i check if its leaking then, im guessing just pull out some of the dash n have a feel. Thats unless there is a top-up tanks that i can look at to see if its empty. thanks

it is the engine coolant in teh heater matrix, i would definately check it if i where you. you could pull up some carpet and see if the underlay is wet?

Hey thanks for the help, just been out for abit of a fiddle and there isnt any sign of leaking. I also re-checked the fan, and its is very dodgy, it is very intermitent, and thats when just connecting it to an exterior power source (not the resistor). Any more ideas on the stero not working, could i have blown something in it when i jump started the car recently?

I find it hard to believe you could've done any damage while jump starting the car but how far & what did you take apart when you stripped the dash bits down?

 

There is a copper sprung wiper that crosses the tracks on the circuit board that is easily lost & stops it rom working.
