As title partners car has no heat coming through the air vents. Blower works on every fan speed. It has climate control so doesnt have the usual resistor. Any ideas

Who knows?
If it has climate control it could be an issue with the temp sensor inside the car?

Different car entirely, but it still may be relevant. A wee Clio I had used to have Climate control, the sensor on them was mounted in a panel on the roof cloth and used to get clogged up with dust and dirt and prevented the heater from blowing out hot air.

Might be worth a look.

Failing that, Google common heater faults with the Altea, that’s how I found out about the Clio’s issue.

Cheers all when we got the car my mate ex vw mechanic done timing belt kit and water pump for me. Is the system not self bleeding? Both pipes at the matrix are hot so coolant must be circulating ok because if not surly 1 would be hot and the other cold
Another friend of mine plugged his computer into the car and nothing came up

Got the blower working but still no heat. So started car and let it run. Was running for over an hr top rad hose was roasting and bottom one never heated and the rad fans never came on. But there was bubbles coming out of the expansion bottle when i squeezed the pipes

Get in under the dash and turn it from hot to cold and see if the flaps are working as they should I think this happened to me and it was a we rod that had come off the arm of the flap popped it back on and all was good again
