blower motor dies in the "High" setting

Sorry if this doesn't belong in here, but I'm having a problem with my blower motor. The switch on the A/C controls has 4 different settings for blower motor speed. For whatever reason, my blower motor will not work in the highest speed setting. All others work. Has anyone ever ran into this problem before? I'd really like to get this working soon so my car will pump out lots of heat... Any help is greatly appreciated. Thanks

Common problem. Consider a search for more info. Relay IIRC.

I'm sure it's the relay (or wiring to it). melted plastic from the connector stuck on the "High" 12v lead in the relay. gonna get a new relay, try to clean up the connector, should work fine. Thanks for the help... Vader always to the rescue with pics and all =) thanks

no your help is greatly appreciated too. It makes such a great difference in me being able to stand cold weather with the t-tops off if I can crank the heat all the way. Thanks
