Random Electrical Quirks on 2000 Eurovan

So a few things are happening but I am not sure they are related:
* AC compressor will almost violently kick on and off when it is hot outside
* Controls for heat/AC blinks after starting for 10 seconds
* solenoid that keeps you from shifting out of park just started failing
* 50 amp main fuse blew while woking on solenoid and it also blew a couple months ago
Any advise on where to start would be great, I'm just going to replace fuse and see what happens.

Thanks, JJ

Are you still having issues?

It appears to me that the first two points you mention could be related. The 'blinking lights' for 10 seconds after start probably means there is an issue within the Climate system and that could be related to the compressor issue. You would need a shop that can access and 'read' the DTCs from the climate unit to find out what the control unit thinks the issue is.

Second concern with the shift solenoid is concerning. You need to have a fairly large issue to blow a 50A fuse and that would be more than a solenoid issue. You said "....50 amp main fuse blew while woking on solenoid ..." so my advice would be to retrace your steps and try to figure out what you were touching when the fuse blew. I would think the wiring shorting to ground would be your issue so try to recreate the situation and see if there are any power wires near where you were working that could be shorting out. For the 50A fuse to blow I would expect to see some evidence of shorting (black marks, arcing on the sheet metal etc.) so a visual check should reveal some evidence.

Thanks

Thanks, so the mechanic found the short at the alternater but it is still acting weird occasionally with the lights dimming for a little while and now it is running rich. I appreciate the advice, I'll be trying to find a better local mechanic.
