Check the fluid level. If it's fine, then a plugged filter would be the next to suspect. USALLY it means U have gone TO LONG BETWEEN CHANGING the Transmission Fluid & FILTER.IF that is good U can try a GOOD Additive 2 soften the seals.EVERY 25,000 the Transmission should B Serviced.
blower motor blows hot or cold air over evaporator
when cold runs fine holding tack at 2500 rpm then clears cylinder
because someone was fiddling with the passenger climate control and now that baffle has stuck in the cold position . I had a 1997 buick lesabre which had the climate control functioning until a friend started adjusting it a few times then it became stuck in the cold position but only for the passenger side It is likely a mechanical bind in the baffle .
check igntion coils
Most likely, the fluid is low, or the filter is dirty.
When my a/c system is low on refrigerant, it blows hot on drivers side, cold on passenger side of the dashboard. This is a 1997 Buick Ultra. Recharging the system solves the problem.
check crank sensor
My 1991 740 volvo turbo doesnt start specially during the morning.Is it comes with a cold start valve?
you might need to change the trans fluid and filter or it may just need a rebuild (inside may look totally different from outside)
yes it is normal for the fan to come on if you have the defroster on or the ac running when you are letting it warm up.
Check to see if you have a dual climate control. There are usually two sliding levers on top of one another. Slide them both to cold
it is a very silly question It's probably time to change the fuel filter - or the fuel pump is starting to go bad.
