a few days ago my a.c. went, when it went it took my heat with it. now its raining crazy and when i turn on the defrost all i smell is antifreeze. even when i turn the heat/cold all the way up i feel nothing, hear nothing, just smell antifreeze. so deos it make sense to spend twice as much and take it to the dealer to get it fixed or should i just take it to a little street shop to fix it that might not even know what the expletive is wrong wit it (im in N.Y.) ohh ****, my fault, i have a 91 tegra gs.
