heat doesant work, when I turn on the ignition the needle goes back words,when motor starts needle ever moves it stays back words. Ben like this when I bought it.I don't know but the curse control will disconnect sometimes when driving & the intermittent wiper some times wont work. could they all be related ??
how can I fix the heat gauge on 1994 Buick Century
No, they are not related. The temperature sender needs to be replaced. The multifunction switch that controls the cruise and wipers is worn out and needs to be replaced.
