yes after i changed the battery the ac blows cold on driver side but hot on passenger side on my 03 silverado

1995 Bonneville, AC and heater only blow through the floor vent and defrost vents, not the middle ones.

Heater Blower Motor High Speed and AC compressor not working. Would this be the fuse located beside the battery (HVAC). Normally I would just replace the fuse but I have noticed a strange behaviour when turning the blower control to high. The interior lights get really bright for a second and if I do it two or three times the ABS light and the Engine light will come on. I have tried to find a wiring diagram for the circuit but was unable to obtain one. I am worried that there is a major electrical fault here.

on our 1999 KIA SPORTAGE, the inside ac blower and all power windows stopped working at the same time..all fused okay..any idea what is wrong? could it be ignition switch? RELAY?

a/c blows very cold with no problems until i shut off car for 5 to 10 min. like to run into a store. then restart the car the a/c blows warm for 5 to 10 min. then slowly starts to blow cold again. whats up with that.

After the AC technician finished AC repairs and recharge, the engine 3.3L  stopped running and a gas odor came from somewhere under the vehicle. Inspection of all gas lines showed no leaks. Fuel pump came on, but no fuel pressure present at the injectors. The scan tool showed a circuit problem with the No. 1 cylinder. Fuel filter is okay as well. Still no fuel present at the injector fuel rail.

i have pumped up pressure to high end and low end of the system with nitrogin and cant hear or see leak. i did try to fill system with refridgerant first and it leaked out in a day and a half so it has a big leak but i am so boggled by this. do you have any advice for me
