    No Heat, freezing :/

    I have been fighting the heat coming on and off in my 96 Tahoe for months. It started with a cracked heater water valve which I replaced followed by a thermostat and finally the blend door actuator. From this post I gather that the vacuum to the heater valve exists to shut off the flow of hot...

    4x4 Fuse Blows

    So it was a shorted front axle actuator. It had been replaced by the PO at some point and used a non-OEM actuator. The wiring connector had been changed too. So it now has the right actuator and connector.

    Starting Problem after sitting

    More Info I once again took out a plug to check spark and had the wife turn it over. It sparked but also looked wet around the base of the plug. I sprayed starting fluid down the throat but it still would not start although it chugs once or twice when I let off the key. It feels like the...

    Starting Problem after sitting

    It seems that my 96 does not want to start after sitting a few days outside and humidity also seems to affect it. It cranks and cranks and occassionally has a little "bump" like it wants to start but doesn't. I have searched the posts and done everything I can think of. If I start it every...
