Re: heater switch problems

I thought i would check out the vacuum lines and found that a number of them were split at the ends so i trimmed the ends off and replugged them in and viola i inadvertanly fixed the heater switch (sweet) didnt know the vacuum lines had anything to do with the heater switch so that was a real bonus,one happy camper i am

Nice fix, you may want to get a roll of vacuum line and replace all of them.
