96' Mark III electric problems

[Mauinix]

I am beginning to have multiple electrical issues. I believe my heater core has quite working, but the relay continues to cycle constantly and I have no heat at all. It's very annoying to say the least. Anyway, I've also been receiving noise shorts over my radio, until the point that I have to shut it off, completely! My CD player cannot be heard at all, but appears to be working. Does anyone know if there is a common denominator or can you just reply with any help with any of the above??? I would appreciate it...

go to http://search.ebscohost.com/login.aspx?authtype=url,uid use asa password library and library select model, year etc, you will get wiring diagrams, and follow the current and wires. i had a problem with the blower turns out it was just a littler connector, found it with the diagram, I hope it helps.

I had some simmilar issues on my 1998.
Heating was a bad blend door.**Replaced**
Noisy shorts was a bad connection on the board of the amplifier under the sun deck. **Replaced amp**

As a follow up, check here for info on the blend door and how to reinforce it:
