My heater seems to warm the passenger side better than the drivers side. The local 'Mucky-nic' has changed the heater valve that is in front of the bulkhead/firewall roughly in line with the drivers position, but this hasn't changed anything. Therefore My question is; Is there just one valve or is there one for each side of the car? Any advice gratefully received. Mike |

Hi, I think there is only one valve, but if you are getting different temps. from different sides it won't be the heater valve but more probably the controls as you have seperate controls for each side Have a look on page 3.10 of your Haynes manual bottom left, Pic 8.4 |

Already tried all that, and I've checked all the heater hoses are hot, so no 'airlocks'. Thermostats have also been changed, but after the engine has run up to approx 90-100 degree's the heater still doesn't blow hot, just mildly warm. Suspicion was on the valve, but changing it has made no difference. Operating the heater controls (both independantly and/or in unison) makes no difference either. Just can't think of anything else to try, except possibly checking the airducts on the drivers side of the vehicle for blockages. Edited by Mike wantza Merc, Sat Mar 20, 2010 6:57 pm.

Hi Mike, Are you saying that the heater never gets roasting hot, on either side even when fully hot regardless of any heater control positions? Sounds like either a scaled up heater core or air in the system. It's still possible to have trapped air in the heater core even with both pipes feeling warm to the touch. Could be worth flushing the system out thoroughly, perhaps even using citric acid to descale it at the same time. You can reverse-flush the heater core with careful use of a hose. Will |
