I m having some strange going ons with my heater. it blows cold until i speed up at whatever speed. within a couple of seconds of accelerating its red hot but then dies off when i ease of the throttle. Im putting it down to a possible vac pipe fault on or to hbv. strange thing is if i rev it when in motion it stays cold, but as soon as i let the clutch back out the heat comes blasting through the vents. the cars temp gauge is doing what it should and the climate control and air con controls are working fine ( tested by turning it to LO and worked it up through to HI whilst in motion.)
had the car a year and think that its had the head off before me getting it cos i had to reconnect a couple of vac pipes back on near the brake cylinder but found another one running across the scuttle panel that was just sat there. take it this connects to the bulkhead grommit but not sure where the other end goes( its got a plastic bulb?or filter on one end and a good length of pipe) does it connect to pipe near the battery/ power steering bottle? if anyone can help i would be greatful cos it bloody freezing and im sick of blipping the throttle to get some heat. cheers.

welcome to oof Chris, there is a guide for the vac system in maintenance section but its for the v6, might be worth a look for clues until a 4 pot owner comes along, i dont know it well enough to advise but def sounds vac related to me as you say. Someone will be along with your info no doubt.
ttfn :-)
