A MECHANIC has warned that "cheap" plastic parts in almost every motor could end up costing owners hundreds to repair.
David Long, who goes by the name Car Wizard, warned drivers that their air-con system could be a silent money pit.
In a video uploaded to his YouTube channel, David used a customer's car to demonstrate the issue.
He claimed that the owner had brought it in due to a faulty heater, which could only be set to maximum or minimum temperature and also wouldn't activate the windscreen defrost setting.
The motors whizz explained that the issue was with the plastic motor that powers the air-con system, which itself is hidden deep in the dashboard.
He alleged: "I kind of new it was probably going to be some issues in the dash with those little motors - and it turned out to be true.

"It was electrical problems with those and it pretty much shut those off.
"This is a common problem that's happening with every single car maker on planet earth.
"This is a problem with all of them because the parts are so cheap."
The issue, according to David, is that the location of these small parts within the dashboard means that, while it may only cost a few pounds to buy a replacement, customers are left shelling out hundreds for the hours and skilled labour it takes to access them.

To fix some of these motors, he claimed, his team was having to pull out much of the inner part of the dash just to unscrew one small part.
As for what you can do to prevent this, David urged motorists to change out the air filter in their air-con regularly.
Doing so, he said, prevents a buildup of dirt and debris in the filter, which would force the motor powering the system to work harder to suck air in, increasing wear and tear.
It only costs around £40 to do this and it is recommended to change the filter every three months.
The Society of Motor Manufacturers and Traders, which represents car makers in the UK, declined to comment.
It comes after an ultra-rare supercar was mysteriously found abandoned deep in the jungle.
Meanwhile, a driving instructor revealed that learners are actually able to use a little-known button to help them pass their tests.
