screeching sound like fan is catching

So, even before I took off to my friend's house strange things happened.
First of all, twice today, the car would not start by touching the wire to the starter...I had to "hook it up," and put the key to position III and then it started normally. However, soon, the car was doing the same thing it had been doing- starting in position II and the starter staying on... Another thing that happened, the fuse for the injectors (also a few other things)- the same one that kept blowing, blew again...Hmmm....Grrrrrr.

I took off to my friend's anyway- he was very concerned with the ignition switch and wanted to see how the tumber section was so we had that all apart (as much as could be without actually taking the tumbler out) and he did the screw driver trick to it and we drove the car some this way without issue. He also looked near the starter and "unclumped" some taped wiring and checked them and also spread them apart... There was one section where the large red wire (always on, live 12V wire from the positive end of the battery) had other wires taped to its outside- I suppose to keep these wires away from the fan blade, etc., but he said, all it would take are two good connections between the Red wire and one of the smaller wires and we would have all kinds of electrical troubles. The solenoid (green wire) was also in that bundle of wires taped to the Red wire. Anyway, all evening, the car drove normally and started normally. He is still concerned that possibly the tumbler section might be playing a role- the key seems to have more slop in there than he would like....but seems he is in agreement with me that if it's a short, it will come back.

I drove the car home, trying to hit every bump I could in the road- so far so good. Everything is connected back like it should be. If the starter begins its thing again, the suggestion is to first, separate the tumbler from the ignition switch and use a screw driver again and see if instantly the problem goes away....if this does not solve it, then we know for sure it's a short from below. It could be that whatever we did tonight has fixed the problem for good- I have my doubts, but am keeping my fingers crossed.

STill working fine after a day- I'm still thinking there's an intermittent short- it just hasn't happened again.
I have tools with me so I can stop and pull the green wire any time. Still keeping fingers crossed.

You must have touched something that was the problem . Know how you feel , hate it when something isn't really found as the cause yet it's working OK but leaving you wondering all the time . If it starts doing it again hopefully you can find the actual cause .

Just an update- Still no issue...
Spent last Thurs evening replacing front rotors and rear pads...
All is good w/ this Volvo. I think I'm gonna put all the parts I left off for the "just-in-case" back on and button this thing up.
Surely it will be after that when this issue rears it's ugly head again!! LOL

You're likely correct , vehicals are cruel like that . You must have narrowed the issue down so you should know pretty much where to target if the issue resurfaces .

Yes, I hope so- putting all the trim pieces back around my steering wheel today- I think whatever it was was solved. Keeps driving fine now!
