Electrical Problem - Fan won't shutoff, fast blinkers, radio

[scottjk]

I'm having an erratic electrical problem. It started with blinkers flashing at a high rate. Thinking it was a bulb out I check them all and they are fine. Then every once in awhile after turning off the key and removing it the heater fan and wipers still operate. The a/c fan will stay on also if it's being used.

I'm also having occasional problems with the radio cutting on and off.

It appears that it might be associated with the ignition switch but before I start testing parts I thought I'd throw it out to anyone that may have had this problem.

Thanks

I normally do not like to just throw parts at a problem -- but considering that the ignition switch is a frequent failure point, common to many of the things you describe, costs less than 10 bucks, fairly easy to install and if it was unnecessary then you needed a spare anyway didn't you? -- I'd be prone to just try it.

Electrical gremlins like this are the worst. Start by making sure you battery connections are soild, then make sure all your grounds as still attachhed, in good shape and clean/tight.

I like to go through plugs, pop them apart, blow them out while looking for water, corrosion or just plain worn out connections, then use some di-electric grease on the connections.
