Heater blower motor
Discussion
My heater motor hasn't worked since I bought the car earlier this year, it's not a problem but I would like to fix it anyway, ,does anyone know how the circuit works?, I guess there is a fuse, relay and selector switch, but which ones are they?, also how do the various speeds operate?, I have a 95 model.
do you think him or his pussy can fix TVR electrics though?Steve D got it right with the electrics, thank you, i separated the connector and found the switch puts 12v to each pin in turn for speeds 1, 2 and 3, i then measured the motor side and had over 5m resistance from the earth pin to the other 3, i also reconnected the two halves and measured the voltage while connected, all ok, so basically my motor looks to be Kaput, where is it? the cable disappears into the left side of the passenger footwell?
Thanks
That sounds fun, i was hoping for cables or fuse problem, i will wait until the weather turns, took it out again today with the roof off as the weather was so good
While i was playing around in the footwell i checked the water pipes, apart from it looks like at least one of them has been leaking i noticed that with the engine hot and running only one pipe was hot, the other just warm, i guess thats not normal and that without the fan on they should be virtually the same temperature, i had the dial set to hot, any thoughts?, the car doesnt overheat when stationary but the temp does rise quite quickly if i come to a stop and the fans cut in after about 2 minutes.

I will give it a go, but not very optimistic, the resistance from motor supply to earth is very high but resistance across the 3 speed options is only 2 or 3 ohms, does anyone know if there are 3 sets of windings or just a set of 3 resistors feeding a simple motor?, 3 resistors for the speeds would explain my readings, i looked at how to access it today, not looking good, theres so much of what looks like white silicon holding that cover in place, i will remove the battery tomorrow and have a better look.
I also looked at the flow valve to the heater matrix, it moves nicely so i guess there must be an air lock causing the return pipe to stay cool, i guess i need to rip it all out and have a look, is there any other way apart from removing the pipes and putting air through it to test for a blockage?
