Fan and heater

[cornishcalibra]

Hey does anyone know why the fan and heater would stop working on a calibra 8v. They just stoped but they will both work with direct power from the battery the fuses arent blown??????????[/b]

Could be a dodgy fan switch, only a few pounds to replace I think. It attaches to the lower back of the radiator on one side. I've never had one detatch itself (but you never know), but I have had them fail before - worth a look!

With the engine warm, does the temp gauge read at what you believe it should, or is it running too cold? Could be that you need a new thermostat.

Na the engine temp shoots up to around 100 if its sitting idle to long

Probably the fan switch then. I can post a pic of what it looks like if any help...

As I'm lazy, I just scanned a pic from the Haynes manual (of an 8v as it happens) rather than actually stepping out onto the driveway to take a proper pic

Haynes says:
<!--quoteo--><div class='quotetop'></div><div class='quotemain'><!--quotec-->If a faulty switch is suspected, the circuit to the fan motor can be tested by temporarily bridging the terminals in the switch wiring plug, and switching on the ignition. If the cooling fan now operates, the switch is faulty and should be renewed.<!--QuoteEnd--></div><!--QuoteEEnd-->

Na it aint the switch checked that and tryed a new one it must be somewhere else so anoying though????????

Check your pollen filter. It can get that blocked that the fan makes a blowing noise but no air comes out. Take the filter out and try it. If it works, go and get a new filter!

Ahh, hold on, I think I misunderstood the problem...you mean the blower fan! Sorry!

Wasn't there some kind of problem with the resistors in the motor that crops up occasionally? My car apparently had this, but the last owner fixed it so unfortunately I'm not sure of the details. The info must be here somewhere though...

Its both they both stopped working at the same time main cooling fan and the blower?????
