HEATER NOT WORKING ON ONE SIDE OF CAR

[Kirsty1993]

Hi all

Looking for some help with my seat. It firstly went into the garage as the heaters stopped blowing hot air. They changed the heater matrix as the (bag) in coolant tank had burst so this was all cleared flushed and new heater matrix fitted. So when the car was returned the heaters are now blowing hot air for about 2 miles from the driver side and staying hot constantly at passenger side. The garage cant seem to fix the issue so thought i would come on here and see if anything has had any same experiences or any advice how to sort this?

Thanks

Maybe an airlock? Can you hear gurgling behind the dash?
These normally work their way out of the system eventually - but ideally should have been vacuum filled after flushing the cooling system.

Did they fully flush your coolant system? There is so much gunk in it that even if the matrix has been changed, it could get blocked again.

Did they definintely fit a new one and not try to clean the old one?

What was the total charge for the work they did?

Only asking as other people have had work done/not done that affected the overall outcome.
