The car rides smooth once it's moving but you have to hit the gas really hard to get it moving.

Nothing in the HVAC system is working - no heat, no fan, no A/C. Have replaced A/C control unit in dash and then the passenger A/C control panel in door, but the system is just not responding. The panel (in center dash) is completly black and silent.... We can´t even see the outside temp on the panel.
What to do? Someone suggested to replace the HVAC programmer but, we can´t find one anywhere. GM discontinued it...

try everything new battery, starter

My 1991 Buick Park Avenue cuts of after driving a few miles
What could be the cause

This started happening about 4 days ago. I have to step on the gas and the break to keep the car on. When it just idles it turns off, and also when I start from a complete stop. Please help. Thank so much

My ex replaced my original radiator with one from Ecology (the junkyard). Its from a car that looked just like mine, but the difference in the radiator is that it has 3 rows instead of 2(i really dont know what that means,but thats the way my ex described it). It fits good and works really good, but the problem is that now my fans are not turning on! We connected them to the battery and they ran, so according to a general motors manual, it means that the coolant fan switch is defective. The fans worked just fine before he replaced the radiator, so could the problem be the difference in how many rows the radiator has? And the most important question we have is where exactly can we find this coolant fan switch? Again, the manual says its mounted on the intake manifold, near the distributor. Although not a certified mechanic, my ex is very mechanically inclined and has worked on many of my cars as well as his own and others', but e cannot locate this switch for the life of him, so please explain carefully and if not can you direct us on how to get a diagram of where it can be found? It would be extremely appreciated as I have 5 kids, am a single working parent, and am economically challenged(to put it nicely). Thanks again for your help in advance!
P.s. My ex also checked all the fuses and they are all good.

Buick Park Evenue 91, wont accelerate. In reverse it accelerates just fine, maybe not exactly the same as before but still ok, but in forward it seams that it is in higher gear than it should be. It eventualy comes to 100 mph but even than it has no good acceleration. Only in reverse it accelerate ok. Also the sound from engine and exhaust is not any more so strong and powerfull like it used to be before. Problem is I live in Croatia (Europe) and here is no good mechanics for Buick car, so I'm prety much on my own and help from internet. I can order part from US but first I have to diagnose the problem. So far I only fill up transmision fluid because it is leaking and it was way below it should be, but nothing changes. Thanks, Simon.
