Heater Problems
Heater Problems
New problem has started and I am a bit stumped with it. I recently replaced the thermostat in the cooling system because the car wasn't reaching temperature properly. New thermostat fixed that, but since then my internal heater hasn't worked properly. Only half my vents (drivers side) are blowing warm air through. Even the centre vent is half warm half cold!
I also have a air lock in the radiator system, I can hear the bubbles moving about when I set off. Would this be causing my internal heater problems??
Help! Its too cold at the min!
My car is shocking at the min, everything seems to be breaking or wearing out!

Then top up the radiator. It also helps to have the heaters on full whilst doing this to get the heating system running as well.
If you have an air lock then yes that is most likely the cause of the problem, best idea is to let it cool down, take of the radiator cap and then start the engine and then run it until it is warm pumping both the pipes intermitantly to help it bleed through.

Thanks everyone! I thought that what yo have suggested would work, but didn't want to run the car with the rad cap off, as I have never done it before and didn't know what would happen when it got hot! But will give this a try at work tomorrow, got some ramps to get the nose up in the air too.
James if the above dont work then you may have a servo flap fault but do the obvious first.
When you say centre vent is half hot and half cold do you mean cold air from one vent and warm from the other one or just luke warm from both??

When peolle say have the heater on full blast that does not mean the fan speed, just the temp control to max. seem so many people turn the fan on full blast, all that does is take heat away from the coolant and takes twice as long to get up to temp.

The gurgling sound you hear from the heater is generally insufficient coolant and the noise is the coolant flow thro the matrix mixing with the air pocket at the highest level

Defo sounds like a servo control fault, i have heard of this problem plenty of times before but can not remember the cure for it. I will try and find out and post up on here James. But do try the obvious first and get rid of the air.

Just as an additional tidbit, I heard that if you're trying to bleed air out of the rad system it's best to do it with the front of the car jacked up in the air a bit. Either that or the car on an upwards gradient. Helps to separate the coolant from the air apparently.
