The cluster switches on our cars are starting to show their age these days. My cruise control switches started going intermittent with the RES+ failing totally each time I drove more than 30 km or so down the highway. When tested he RES+ terminal on the CC module was getting a signal from the...

My VQ's air handler is in bits for an evaporator replacement- due mainly to it being covered with dirt and composting leaves. I don't want this to happen again and I'm looking to installing some kind of cabin air filter to keep the evap clean. One location for a filter that will clean both...

As most of us know , VP/VQ AC evaporators are now impossible to find. Given the cost of replacing an evaporator I didn't want to use a second hand unit so Pasino Radiators in Brunswick cut the mounting flange off my old VQ evaporator and welded it to a VR/VS item using especially fabricated...

Anyone have any idea on what would cause the worm gear set in a cruise control module to grind out like this. The gears were perfect when I pulled the module apart to fix a dry joint 3 years ago.

My climate control hot water valve is not consistently shutting off the hot water supply to the A/C box when I set the controller for maximum cooling (18 deg C). Generally it will initially operate with the hot water valve fully closed with the 18 degree setting but if I then increase it a...

I rebuilt my cluster about a year ago using parts from three other clusters and plenty of araldite to repair the cracked trip computer plastic case. Recently it has developed a black spot in the upper LH corner of the trip time window. Does anyone know what causes this- araldite solvent...

Over the years I've had problems with the neutral safety switch locking the engine out from starting after a long 110- 115kmh run on a hot day. Ive replaced the switch with second hand ones and rebuilt a switch following instructions posted on this forum. I've adjusted the transmission...

I have the dreaded VN/VP/VQ upper front boot leak which I suspect is due to a leaking rear quarter window seal. Does anyone know if it is possible to reseal a VQ rear quarter window without removing the chrome and rubber mouldings ? I've got a sneaking suspicion that if I break any of the...

My VQ cruise control stopped working. When I test it by holding down the brake pedal, 'Set-" and "Set+' simultaneously , as recommended in the VP/VQ maintenance manual, the cruise light comes on for a few seconds and then drops out. I'm testing it with with one back wheel jacked up and...

Hi, I'm having problems with my VQ cruise control. It's passed all the tests in the GMH manual except for the speed sender voltage. Holden say it should vary between be 0-12V as the back wheel is rotated at the CC pink and green terminals . I'm getting 8-10V. My speedo works and there's no ECM...

I recently removed my instrument cluster to check the voltage regulator for dry joints and replace the temperature gauge. When I reinstalled everything the car started making intermittent beeping sounds- like the handbrake on warning alarm - when driving forwards. The hand brake light does not...

GM has finally decided that Holden will be no more: https://www.theage.com.au/national/government-slams-holden-for-unacceptable-decision-to-axe-brand-20200217-p541lt.html I'll hang on to mine - and I also like football, meat pies and kangaroos.

88GreenVN said this 10 years ago "You can swap the Series 1 LCD screens (thin numbers) over with fat numbers (Series 2) - but they must go in the same spot - as in the middle LCD must remain in the middle - as with the left and right LCD screens. " Is this correct? Is there any way to identify...

Hi, I've got my instrument cluster out and while I'm repairing the sticky gauges I want to replace the Neo Wedge T4 globes in the trip computer, which have started to fail. Does anyone know of a source of Neo Wedge T4 halogen globes? The halogen globes have lasted 27 years , can be dimmed and...

Hi , I've fitted a changeover power steering pump to my VQ but the steering still relatively hard and doesn't seem to be speed sensitive. I suspect the changeover pump is for the standard power steering system and incorporates the standard outlet needle valve. There are no part numbers on the...

Hi all. I recently replaced the power steering pump in my 5 litre VQ. I doing this its return hose developed a leak from a split in the lower section where it joins the steel pipe to the rack. I've removed the hose but two jubilee screw clamps on the lower join were almost impossible to access...

Did a 150km run down the Hume this afternoon and when I left the Tulla the power steering was very heavy- like when you've thrown a PS pump belt. Checked pump belts, & fluid level, steering components and tyre inflation- all looked OK. The current pump has done 120,000 km and it's fluid has a...
