Heater blower!!

A week ago handbook came up on Aircon screen and fan would not blow very hard on full speed setting. Still getting a breeze but no full power blast.
Climate control all workin OK on temperature settings, just cannot get the full power blow.

Turned onto drive last night and suddenly fan kicked back in on full power & Legend disappeared off screen .......left car for a day or so. Now gone back to same state as before.............any clues anybody.

Is it also worth getting a re-gas at the local Kwik-Fit??

Cheers

I know nothing..........Check the brushes in the fan motor probably worn out and making full contact on bumps or bends. ..........now you know nothing

I know nothing ................if you have some technical ability brushes can be replaced using new. Or if not available if the motor is supposed to a sealed unit go to a motor factor obtain similar size and mod to fit . ...............now you know nothing

Now i know nothin,, i think, well maby summat (to check the brushes)
A had same sort of prob once, but found that it wis the switch in the control itself that wis fooked...

"summat up i know nothing" but am help full ................."now you know nothing"
