B4 Issues

Postby b4_sonic » Mon May 04, 2015 1:40 pm


New to the forum.

I have a 2001 B4 and I've got a few issues with it that I want to see what can be done to fix them.

My heater doesn't get hot but heater hoses going into firewall are hot. How to fix this?

I have a sreach coming for the passenger front speaker since replacing the stereo which is starting to get annoying now. Still running factory amp and amp plug to stereo was cut and soldered to the new stereo plug. How to fix this one?

And lastly I hope
Lately I've noticed when I release the handbrake when idling at the normal point it drops its revs and sounds like it's almost going to stall and I want to fix this one asap

Heater tap sounds like it's not getting or maybe not stopping vacuum.
I'm not sure with Subaru but my old car had a vacuum hose that opened and closed the tap.
Can pull off the vacuum hose and see if it starts flowing.
See if can feel any vacuum putting your finger over it.
No idea where the tap is on your car but my old commodore was on the fire wall

I do not want to believe it, but it's going to try to follow.
