Rawhide 0 Posted July 10, 2003 my '93 VR6 is suffering from the apparently common problem of the heater dial not being able to select the windscreen setting. I took the whole assembly appart to regrease the cables behind and managed to get some grease in there. I didn't completely remove the heater matrix, I just removed the ashtray, ashtray holder and cigarette lighter and then managed to get access to the rear of the left hand (vent position) dial. In true Haynes style re-assembly was the reverse process and I was pleasantly suprised to see that the heater was now working perfectly.... .... or so I thought :? I then realised that the blower was only operating on position 4. I decided to attack i t all again and when I pulled the knob off the heater burst into life :roll: Now the heater works fine in all four speeds provided the plastic dial is removed :?: as soon as i put it back on I only get speed 4. There aren't any electrical contact on the plastic knob so I don't know where I've gone wrong :cry: I hate electical faults, do I need to take the whole assembly out after all?

vr6storm 0 Posted July 10, 2003 a long shot here :idea: .....but the dials you took off.....did you put them back in the correct order........as they will physically fit but won't operate properly if say you mixed the speed control dial with the direction dial Quote Share this post Link to post Share on other sites

CHEERS! :D Quote Share this post Link to post Share on other sites
