There is a resistor pack for the heater blower - this is the reason for only having 4th speed setting. Replace this and the blower will work properly.
The heater should still blow hot though - does your temp guage still read ok and is your coolant level ok.

Hello Dave,
My neighbour has the same problem with his Laguna blower motor only blowing fast. I have offered to look at this with him but have little or no clue where to begin. Is this a big job or can anyone with common sense do it. Can you please steer me in the right direction and give me some idea how to go about this task and what to look for.

Regards
Dave J

Hi DaveJ,
If you can post the vehicle details I will find out the location of the resistor pack for you.
It will be in one of two locations - either under the dash behind the glove box, or it will be under the bonnet at the bottom of the windscreen behind some plastic trims.(passenger side)
Once you have located it, it will simply be a case of disconnecting the old one and plugging in a new one.

Regards
Dave

Here hopefully is the location of your heater motor resistor pack :

It is normally mounted into the blower fan "box", you will see some wires going to the blower motor and some to the resistor pack, unscrew the resistor pack and unplug it, plug in the new one and away you go...

I think you might find that the coldness goes away once you can select a slower speed. The fast speed will be cooling the heater faster than it can warm up.

it is very common for the fan switch to go,the no heat is also a very common problem your heater matrix is blocked ,this may need replaced or you can try and flush the cooling systen ,there is a double water pipe at the offside at the bulkhead ,it is a little tricky to get off but you can put a hose into one side then the other turn the hose quite fast

Hello Scott,
I have had 2 experiences of this and 1 cost loads and 1 cost less than 2.00. Depending on the age of the car and where the air bags are located. The cheap one was on a 2.2 P reg diesel and getting at the motor involved the removal of the clove box only.
On top of the motor is a resistor pack which is on a bayonet fastening to the motor. Disconnect the wiring and turn it anti clock wise and remove. If you take this to renault they will charge you 60. ish, you can either go to a breaker and get another one or replace 1 of the thermal fuses as I did for 2.00 for 5 fuses. the choice is yours. the fuses came from RScomponents. Allthough this is a fix, it may also be a symptom of something else such as a clogged up pollen filter or a clogged up ventilation system. Any problems get bacck to me.

The fuses are located at the top of the pack, next to or in between the coiled parts. They look like a piece of wire bent at each end where they are soldered to the unit and have a little bit in the middle of the wire.

My Renault Laguna 1.9dci - heater blower has problem. Air is hot, but there is no noticable increase in airflow through the airvents when i turn the fan setting up through 1,2 3 & 4 settings. The fan sounds as though it is faster but the airflow doesn't increase! I have checked airflow at each of the vents - windscreeen, face, floor and cominations of these and it is the same in each case.
Any body have any ideas what may be the problem?
