only getting very slight heat from the heater

[mboon]

As a I've. Any ideas why. Car warms up fine

I'm afraid its probably the heater matrix matey. Hit the search button for more info.

It could be the coolant pressure relief valve thats knackered. Have a search on here for that and i'm sure it will lead you in the right direction.

The matrix's are known to fail on the mk2 arent they?! It did on both of my old ones. Maybe the thermostat if your lucky?

Check the heater pipes by squeezing them and listening for crunching. The pipes can fir up inside and restrict the flow. If the pipes are like that, then the matrix is sure to be the same.

If your car has the bypass valves they could be faulty..

More likely the matrix... Feel your passengerside carpet... If it sodden it's 99.999999999999999999999999999% matrix!!

Feel your passengerside carpet... If it sodden it's 99.999999999999999999999999999% matrix!!

Or 0.000000000000000000000000001% drooling over a 1.4 MKIII with 13 inch steels.

Would have to be alot longer than that before I even looked at a Mk3.... Without laffin and feeling sorry for the owner

Could just be a problem with the arm on the heater box. try moving it by hand and see if any more heat comes out.
Has any foam blown out your vents?

Thanks all
 carpets are dry
No foam coming from the vents etc
We are getting some heat its just luke warm. The fan seems to always be on when we park it up but we di have to go slow for a few miles as road bumps. Any way of testing the matrix
