the 25? amp fuse to the aircon gets extremely hot and melts the plastic, but doesnt pop.
Have had the use of the 3 and 4 speed on the fan till yesterday and have been ok with that.
however yesterday the fan stopped working altogether so pulled the resistor thing with the cage on from under the windscreen wipers and it has one burnt out wire, so in theory I should still have 2 speeds or at least 1.
my next thoughts were the switch on the consol or the blower motor.
I lean towards the blower motor because of the heat being generated and melting the plastic on the fuse might be caused by bearings in the motor seizing.
Any tricks to getting the blower out, like does the aircon have to be disconnected, or is it a fairly uncomplicated operation?
Also should the sender unit on the V8 fuel tank be easy to get out?
I got hold of a big tank but the fuel sender seems determined to stay in, no matter how I twist and turn it won't come out. anyone else had this problem?
thanks

Blower fan faces the firewall, so the HVAC box has to come out to get to it (or moved back in-situ, but this still requires degassing).
Tank senders need the return hose (on the inside of the flange) disconnected (don't drop it) before the sender will release. You have a wagon don't you? All their tanks are the same 68L size, it's only sedans that had bigger tanks available (size depends on the model). |
Cheers,
Mick

Thanks mick,found the problem, the melted plastic on the fuse socket was stopping the fuse making proper contact so fortunately don't have to remove blower..yet..
but resistor is definitely shot has one speed only.
Was thinking of getting some resistors from jaycar or whatever and soldering them across.
The tank is definitely deeper than the one on the car, (wagon) I measured from the join and it is about 50 mm deeper. till i get the wagon one out I don't really know if it is a wagon one, looks the same, but, can't believe everything you are told buy a seller.

Wagon tanks are an odd shape, as they fit a thin section under the spare wheel area, and a big box section to the side of it. Sedan tanks (VB-VS) have a flat top on them. VG-VS ute use what is basically a sedan shaped tank with a different filler entry point arrangement. VB-VS tanks are all effectively the same style throughout the 21-22 year lifespan (there were numerous small changes throughout production, but with minor mods, you can retro-fit later tanks into earlier cars quite easily). Here's some ebay listings that show the difference: Sedan: http://www.ebay.com.au/i...N-VP-VR-VS-/321240512009Wagon: http://www.ebay.com.au/i...WAGON-ONLY-/171173486196 |
Cheers,
Mick

For the fan speed resistors, be careful - they are very high current, so you'll pop an under-rated resistor very easily. They are open coils, exposed to the airflow, to allow them to be cooled - which is critical to their ability to handle the high current. I would not be willing to risk it, when replacements are easy to source. Rather than trust 2nd hand wrecking yard items, you an buy new ones. Newer replacement ones are a solid-state design, such as this one on ebay: http://www.ebay.com.au/i...-BRAND-NEW-/230986931597Or give Dr Terry a call on 02 9644 2888 and he can mail a new one across to you. |
Cheers,
Mick

thanks Mick but that takes the fun out of owning an old bomb, you can play with it, and whats the worst scenario? a 50 cent resistor packs up. its not going to catch fire or wreck the wiring. I like to pull things apart and make new things, thats why I made my own taps for the shower and bought a lathe.
for the tank I am away at the moment so will have to wait till next week to compare the tanks. my alzheimers has kicked in and I can't remember if it has a hump or not...burble burble burble...

Did what I usually leave till last, read the instructions.
My glovebox handbook for the commodore calais VR series says sedan has 63 or 75 litres, all wagons 68 litres, and all utes 64 litres.
incidentally often you spot little things when doing something else, while working on the fuses I noticed it had an extra 25amp fuse, checked it and it was in the radio socket. the recommended fuse is 7.5 amps.
The 25 amp fuse is clear plastic, the 7.5 is smokey grey but transparent, in so-so lighting they are easy to mix up.
Memory has kicked in, pretty sure tank does have a hump, it may be out of a later model.

From VT-VZ, they went all plastic tanks in sedans & wagons, and both types look like the VB-VS wagon steel tanks with the hump on one side (thanks to VT-VZ sedan having the spare in the boot floor, like a wagon).
So basically if it's metal it's up to VS, and plastic is VT onwards. You can't put a plastic VT one into an earlier car. |
Cheers,
Mick
