The heater fan comes on in the cabin when heater is switched off no lights on the unit totally switched off but the fan inside the car will run for abou 5mins, go off for like 30 secs then comes on again until I switch the ignition off. Switching the engine off the engine fan kicks in and drains the battery, on a normal drive the temp gauge reads normal, air con is ok too, when the cabin heater is on, everything works as it should just these two faults.
Thanks for your reply, maybe I wasn't clear in my question, I'll start over, when starting the car the cabin fan comes on and it's switched off, it goes for about 5mins the switches off for about 30secs then comes back on, still switch off. The engine fan is working but when I switch it off the engine fan runs for a couple of hours running the battery down. I've no idea how to fix the problem so any help would be appreciated as costs can sore.
