Cupra 280 Heater Issue?

[ben]

My Leon Cupra 280 seems to take a while to get up to heating temp. Where I must be the Driving car in excess of 10 mins. Then it heats up fine

In the meantime, cold air con works fine, and works fine when up to speed.

While the car is warming, there is a point where the heaters blow warmish air; if I then crank the heaters or fan speed, the temperature gets colder for a bit, until up to full temp.

one blower is cooler than the rest but eventually gets there

I thought it was due to a thermostat housing leak that I had interfering with the thermostat function. I’ve just had that fixed today but the issue remains

any ideas? Heater matrix? Blockage somewhere? Other?

Thanks

Are you using it in Auto?

Mine will refuse to blow anything until the car get sup to temperature. This is nice because it stops the car blowing cold air in to the car until the car heats up.

Try setting the temperature to hot and turning the fan up and seeing if it makes any difference?

But auto makes no benefit
