Please don't say, "they all do that, sir"!!

There must be a waay to get my '96 Griffith to blow out something resembling cool air? Indeed, anything that doesn't resemble the exhaust from an F-14 on afterburner would be a plus.

Also, the dash, buttons and door levers are scorchingly hot (well actually just very, very warm). Is this normal?

"They all do that, squire"


Seriously though, I find trouble getting a decent heat out of my vents which seems to be a more common fault.

Think yourself lucky over the winter and post this thread again in about April/May nexy year!

The 500 chucks out so much heat it's asking a lot for truly cold air at low speeds, but at faster speeds, if you're still getting hot air, there's a flap valve which needs to be adjusted between hot/cold. Can't tell you any more, but it has been discussed before on PH.

Manual aircon system and minimum speeds of 60 (summer), 40 (spring and autumn) or 20 (depths of winter, barring ice and snow, but with silly hat).

Cured!

Edited to add 1) add ten mph for Hampshire and 2) who do you head compliance for, Bernie?

Have you tried opening the window or taking the roof off??
Mine only blows hot too - very useful from now until the end of April. Either divert the heat away from you or roll the dial around to stop the vents blowing.

Strangely enough I worked with a Tuscan owner (no that's not strange is it? ) who kept a blanket* in the car to keep him warm in the winter even with the top on!!! Apparently his (early) Tuscan was useless at heating the cockpit - his second Tuscan (an S) was much beeter, though, just proving that each example is an individual.

*And no - he was only in his thirties!!!!

I adjusted mine, pretty easy really. It's the valve that controls the flow of hot water to the heater matrix. The adjustment is to ensure that it is closed when the dash knob is set to cold. The valve is fitted to the end of a spindle on a servo motor and there is a handy white blob of paint at the cold position. It’s all tucked up under the dash on the passenger side, easier to get to if you remove the glove box. I just re-set this by loosening a grub screw. Bingo - cold and hot air all summer. Rich...

I looked at mine the other evening, the white marks line up when set to cold, spindle turns approx 1/4 revolution when changed to hot....

When set cold no cold air any clues?

1/4 turn would be right, it's like a gas tap or one of those on/off cocks for washing machines. No idea why you still get no cold though? Rich...

Thanks for the tips - I will check the flap valve. What about the heat of the dash, door levers and such - is it a case of "they all do that"?

Off to the silly hat shop I guess!! Seriously, I cannot find a way that the scorching air doesn't flood the cabin. Roof off and moving is better but still a brief stop for a red light causes the sweat beads to form!

If HSBC is so good at knowing what a rude gesture looks like in Uzbekistan, why do I only get 0.00000001% interest on my current account?

Dunno Simpo Two. Tell you what - give me your cash and I'll up it to .1%. Can't say fairer than that! Of course, I may abscond to some south pacific island (imagine the welcome they would give the Griff in Hawaii )

My 500 is a bit on the warm side too. Do you need to also remove the dash to get to this valve, or just the glovebox ?

Just the glovebox, it's up above the battery and fuses etc. You will see the black rubber heater hoses with the valves on even without removing the glovebox if you look up under there. R...

Sorry didn't mean to turn it into an HSBC bashing thread guys!!!


(Just an out of work Compliance expert wondering where the next dribble of Optimax will come from )


They really DO all do that, Sir! Was in two minds about getting the top of for the M'way trip to Bristol and back today. Opting for the "it might rain" preference, I reckon I was in a chance of staying drier anyway with the roof off and a twenty minute downpour... ...if you know what I mean!

(thank goodness for anti-perspirants! Yeah "Sure" )

Actually I have no complaints with my First Dircet account. I just can't help thinking that if they didn't spend millions on silly advertising we punters could get a bigger share.

Following on from Badman's idea, if anyone wants a guaranteed 50% return from the lottery, just send your £1 coins here. I'll send you 50p by return. Much better than throwing it away, no?

I think Mr N. Lan-Drevenue patented that idea some time ago......

THe old heat, heat, heat. I'd heared that around 1/3 of engine power goes in mechanical losses, 1/3 in heat and (finally) 1/3 down the road. So a top Griff 500 is shoving out 100 BHP in heat - something like 75KW. That's 75 kilowatt heaters under the bonnet. Surprisingly it doesn't all melt
