heater

[Little_Paul]

Had a search couldn't find anything.
I noticed lately that when car is running the fan speed of heater seems to get quicker when im accelerating and also gets quicker if I turn the lights off , any ideas ? or is this normal for pumas?

I do not know for sure, but maybe it is the other way around, that is the fan is at normal speed when you are accel./not drawing power from else where.
Get your battery and alternator checked, Halfords do a free test.
That is what I'd do first.

That does sound like a battery supply thing.

Although the fan does draw a lot of current, you'll never really completely remove the change in speed with the engine on/off, some variation is normal.
