Title: starting question 85 Jetta Diesel
Post by: dyoungen on October 12, 2009, 07:05:15 am
Hello again. I have a 1985 Jetta Diesel that I thought had a bad starter. I pulled it and took it to the auto parts store, O'Reillys, and it checked ok. What else could it be? When I would turn the key to start, it wouldn't do anything, no clicking, just silence. Ignition switch?

your battery, or check the connections on your starter also, I put a new one on my AAZ and it wouldnt click but then I reliezed I had the connections mixed up. Also Try jumping your starter with a screw driver?

The battery looks like it just came off the shelf and I checked all of the connections. Right now I"ve got to get 2 bolts to replace the starter bolts. I"ll get the 2 bolts and recheck everything again.

I think no sound at all is usually no connection at all (as opposed to a bad connection or low charge).

Did you take the battery cables off and clean/inspect both ends? How about the connection from the ignition switch on the starter? That wiring is 25 years old.

Another source of poor connections is the negative cable connection at the engine block. They are dissimilar metals IIRC and corrode. It could also be the ignition switch, they seem a little fragile on these vehicles. It may be time to find a test light or multimeter and an assistant. There is no seat belt switch on a 1985 model but there could be a neutral safety switch on an automatic car (did they make them then)?

If I don't get rained out tomorrow I"ll put everything back together. The starter checked out good and I bought 2 bolts to replace the capscrews that hold the starter on. This is the first time I ran across a starter that bolted through the engine block and threaded into the motor mount.

Finally dry weather:)  I checked the small wire on the starter and I don't get anything at any time. I used a jumper wire to the small termanal directly from the battery and she started right up. The starter and battery are ok, I"m just not getting 12 voltes to the small wire on the starter. I followed it to the firewall and then................... it disappeared. I'll be getting a manual shortly.

Yeah, but it sucks when you get to that first turn and the steering column goes click and you go careening over the embankment because you didn't have the key and the steering column locked...   ;D

Someone hotwired my golf last year when I was working I walked outside at 12AM and found my car in the middle of the parking lot with the wires for ignition system(home made) ripped out. L:ucky I know who did it...they found his truck stuck in 3 feet of mud...

When I turn the key to "run" everything comes on like the idiot lights but when I turn the key farther to the start position, nothing happens. I checked and the small wire that goes to the starter doesn't have 12 volts when I turn the key to "start". When I run a wire from the  battery post to the small terminal on the starter, she starts right up.

Sounds like your ignition is finished, you have 2 choices, run a push button start from your starter to button to the battery or 12V source when Ignition is ON, Choice 2...By a new ignition and have 2 keys and big red ENGINE START buttons ;D

Based on this evidence there's a 99.9% likelihood you have a bad ignition switch.  Ignition switch failures are very very very common on MK2s and MK3s... did I mention they are very common. ;)

The part that needs to be replaced is just the electrical switch.. the key tumbler stays in place and so you won't need new keys.

It's a 10 buck part but is a bit of a pain to remove since the steering column has to come out and this may require a puller for the steering wheel spline adapter. Search for "ignition switch" over on the MK2 VW Vortex forums and you'll find 3 or 4 really good pictorial HOW-TOs.

I have a steering wheel puller, would that work? I have already removed heorn button, found out the horn doesn't work .

A steering wheel puller won't work for the part Vince is talking about.  However, I don't think they started using the adapters until about '88 so your '85 might not even have it.  :)

The steering column shouldn't have that press-fit adapter "collar" on a 1985 model, they put it on later models. I thought it went on airbag equipped models but I could be wrong.

If you have this thing on your steering column you need what is called a "bearing splitter" (google it) to grab behind the collar and you use it with a standard threaded puller. The bearing splitter costs about $40 for a good one, I have one.

I ordered the electrical part of the ignition switch and it should be in tomorrow. Bad part is I"m working overtime and might not get the chance to install it for awhile. I checked and the switch from Oreilly's is going to cost $38.00 plus tax. They had one listed cheaper but it out of stock. OEM only.

carry a spare VW key with you. the column wont lock if theres a Key in it, doesnt even have to be the right one. i used the key for my Jetta in my audi to get it to my buddies house. the wheel wasnt locked YET, so i just stuck a key in the ignition to keep the lock form engaging. worked fine. but once its locked, you absolutely have to unlock the ignition, or break the lock pin.
