964 heater help required! please

[james964]

Hi

Have just bought a 1989 c4 cab which is great apart from a heater problem.

Heater was only blowing for 1-2 sec on startup then nothing. I've changed the heater control unit with a second hand unit, the fan now blows fine when setting is on cold but cuts out when the hot/cold dial is turned towards hot.

Can anyone help????

Thanks

James

Ok great thanks. If it is the fan is is it straightforward to change?

Thanks will try fuse first

Problem all sorted.

It was the rear blower fuse had blown, replaced with 30amp and all seems to be well.

This is appears to be the problem all along so I now have a spare heater control unit if anyone is interested?

ok will keep my fingers crossed! It still had the original 25amp fuse but i'll prepare for rear blower problems.
Thanks for help
