My Buick 2000 is having electrical issues. The heater blower will work sometimes on high and other times when shut off can't get it running again. Now sometimes everything decides to work heater blower low speeds and high, all climate controls, and even the cruise. Then once vehicle is shut off does not want to work again. For some reason the cruise issue is tied into the heater blower issue at the same time. Any ideas?? thanks

I have a 1996 deville and the heater doesnt work. A/C works fine the blower blows cold a/c but when i turn on the heater it only blows out by the floor boards and it is cold. the vents dont work only when the heater is on. could that be a coil or??? any help would be great.
Did you buy it used? Could be that the heater core was leaking and was disconnected by joining the hoses or hoses were rerouted. Another possibility is that the climate control valve which limits the amount of coolant to the heater core is not openin ... 1996 Cadillac DeVille

I had a block heater installed [which stopped working ] and now it is overheating and heater is not working at idle, only when vehicle is above 1800 rpm. Did the block heater replace the thermostat and if so should i pull the block heater out and install a new thermostat? thanks.

The engine in my Dodge pickup,diesel cummins, won't start,it has fuel, the manifold heater isn't working and the lift pump isn't working anymore, both were working when we started working on it. I replaced the fuel filter, because it would run for a little bit then die, kept dieing with a new filter so put on a new lift pump, I am wondering if the lift pump and the manifold heater are on the same fuse or breaker. I have checked the fuses and the breakers.
The fuel heater is connected with the fuel pump, if it does not work, the fuel pump won't pump. Manifold heater has separate relays, fuse, and selenoids which are under the driver battery. If you have been working on it a lot make sure the battery is ... 2001 Dodge Ram 2500 Truck
