Start with the trans modulator & see if that takes care of several issues.

OVPR is behind a cover behind the battery.

Thank you M.B.DOC

I'm hoping the modulator is causing the greatest problems, so thanks for the reply.

OVPR is single fuse and keeps blowing it (thanks for that info too, knowing where to look made finding it MUCH easier. LOL). Am I correct that when replacing it, it's best to get one with 2 fuses?

Also, how big a job is the heater core on this thing? Surely not worse than a Volvo 2XX I'm hoping.

Thanks again,
Frank
