Any mechanics out there?

Question

I'm trying to figure out what needs to be repaired on my car... I have a '91 Chevy Corsica that doesn't put out enough heat in the winter; almost no air comes out of the vents and the defrost barely works. If I have the heat and defrost on at the same time, nothing happens. Also, when I turn the rear defrost on, the engine stutters. The engine also stutters when I am idling, with the break on and when in park.

Can anyone help? I can't go through another winter without heat...

Answer 1

well the engine stuttering is because its old...not much you can do.

for your heater, sounds like your blower motor died. had to change mine...i was having the same problem. i did it myself so the part only cost me 90$ (mine was behind the glove compartment which i had to remove).

Answer 2

call your local auto parts store like advance, they are very helpful with all of my car problems, and they don't take advantage of a lady.

Answer 3

With all the symptoms you're describing, it's time you took it in to your mechanic for him to look it over.  You probably need a new thermostat to get the coolant temperature up where it belongs, and it sounds like you're overdue for a tune up also.

It is a 17 year old car after all.

Answer 4

Sounds like an electrical problem because you state there is little to no air coming out,(blower motor), and the idle changes when switched on, (electrical voltage draw).  

Answer 5

There is a control valve that needs to be looked at> Have some 1 there check to see it opening and closing>

Answer 6

change the thermostat. it,s either stuck open part way or you have a too low of thermostat. go to auto zone and ask for a thermostat and gasket for your car, better put some sealer on the gasket too so it won,t leak.
