Vent / Heater / Aircon blowers not blowing

[Covkid]

My blowers on my heater have just packed up on me .......
Its a manual aircon. The A/c light comes on when pressed and when i turn the dial to 1,2,3, or 4 i can here the a/c engaging under the bonnet (compressor) but there is nothing coming from the blowers..
I assume that the manual speed control inside the car is ok because it engages the a/c when its turned up...

Ive tried the fuse in the glovebox and thats fine..

Ive searched across the forum but I couldnt find anyone that had posted the problem before...


I would appreciate any help or general guess's you guys could offer, as the misted windows are driving me mad

have you checked the relays too?

have you checked the relays too?

I havnt. Are the relays the ones under the fuses in the glovebox???

Is it just take out the relay... replace... listen them engaging?

Is there any more fuses under the bonnet that have anything to do with the aircon/blowers?

I have just noticed that when I accelerate hard i do feel a bit of heat coming from the vents... Could that just be heat from the engine bay coming through???

[Covkid]

Has anyone got any ideas at all?? Any input what so ever, would be appreciated...


Does anyone know anything about the heater resistor and its workings??

I think I also have the same problem, I was driving with the heater on full then realised that it had gone cold. When i checked the blowers were not blowing?
Tried the fuse inside the glove box and it appears fine, does any one know which relay is for the heater blower and also is there any fuses under the bonnet that would stop it working.
Did you sort yours in the end if so can you offer any help?

5F (7.5 A)
+ After ignition passenger compartment: gear lever display - ECO/PERF
switch - cruise control and speed limiter - driving instructor's control unit -
passenger compartment relay and fuse unit - passenger compartment
auxiliary heater relay - diagnostic socket - hands-free carphone microphone
- rear-view mirror, rain and light sensor (depending on version)

This is located on the Protection and Switching Unit (Fuse and Relay board to me and you!) underneath the plastic cover in the engine bay.

There is an additional fuse box located underneath the PSU:

(1) - Not used
(2) 40 A Preheating unit
(3) - Not used
(4) 70 A Passenger compartment fuse and relay supply
(5) 50A Anti-lock braking system computer
(6) 70 A Electric power assisted steering
(7) 40 A Auxiliary heater relay
(8) 60 A Passenger compartment fuse and relay supply
(9) 70 A Passenger compartment auxiliary heating relay

Have you lost any other functions?

In the glovebox fuse box, the top relay is for the electric windows and the bottom is for accessories.
