This here might be something to look into.

I had the same problem with my 99 SVT. Went to the dealer and picked up the part for 14.00 and took about 30 minutes to install. Everything works fine now.
Both recalls have expired. I ended up replacing the resistor pack and that solved the problem. Mine was noticably bad since part of the resistor was cracked.
