1992 VP Cooling Problems

It won't have a speedo cable. The speed sensor is a round black plug thing at the back of the transmission with three wires coming out of it, make sure its white plug is plugged in to the wiring harness. The plug connectors are 3 sets of plugs at the back of the dash cluster- to remove the cluster you need to follow the instructions on this forum. You have to be methodical and careful of the old plastic.
I have a level 3 cluster and i find I don't have to remove the steering wheel if I turn the wheel so it's pointing down from its normal position and the bevel on the hub is at the top. The cluster can then be slid over it and out to the left.
Break, clean with contact cleaner and reconnect all the cluster plugs. Make sure all the plugs are re fitted tightly.

Don't worry about the questions- we all had to start somewhere with our first cars.

 

If you pull the cluster out you may as well touch up the soldered joints in the voltage regulator board with a fine pointed soldering iron- see the link above, and carefully lube the gauge spindles with silicon spray- don't overdo it and keep it away from the trip meter if you have one.

 

Old diy trick for temp/oil/fuel gauges is to earth the wire out then see if gauge goes to highest setting then back to lowest when unearthed..if it tests out ok then get new sender unit.

Dry solder fix works for awhile,expect issue to come back after a year or two...while your there replace odometer cog if plan on registering it.

 

If the odometer and trip meter are working the speed sensor must be working. On mine the speed sender sends the same signal to the speedo and trip computer.
My speedo gets the following signals from wires to the cluster;
speed-violet/white wire
power-pink/black wire from fuse 10
earth-black wire
If everything looks good have a look at the plugs and the PCB on the back of the cluster for small cracks across the tracks, especially where it's bent or been rubbing.

 

Door locking wiring may take a bit of sorting out like the cluster. In the meantime can you deadlock the driver's door by turning the key until it is flat- this should mechanically lock the drivers door and electrically lock the other 3.

 

It is, the best cluster is called the level 3. What's your present cluster got? You need to to look into the how to's on this forum to see what's involved. Be careful , level 3 clusters are getting expensive as you need to find one with all of the LCD's along the bottom & the trip computer working. These are expensive to fix unless you know what you are doing- a bloke on ebay used to charge around $ 400 to fix them.

If you just want a tacho maybe settle for a less expensive , lower spec'd cluster- it should just plug in.

 

The body looks good- that's what costs real money to fix. You want to check out the nearby wreckers for parts- to get an idea of where best to spend your $250 on parts. And a good wrecker can give you free advice- try and find one with gray hair.
