i have a 1995 buick lesabre that is acting up. the heater controller, the thing which controls air flow, temperature, fan speed, etc. has been beeping and has stopped working, ive gone through two of them that have done the same thing. this is the third. i pulled apart the first two and found that where a resistor was sautered to the motherboard, it was broken. i tried re-sautering, only for it to work for a couple days then break again. i recently got a new stereo in the car and every unit has lasted for about 2 weeks before acting up. so if you know anything it would be appreciated. thanks!
