the fuse is in panel with other fuses,however it will say a\c instead of heater. You may want to use a test light to check for voltage at the blower motor plug. To see if current is going to the fuse. Check the other fuses too. since they are linked in parallel to the the acc auto climate .

Replaced Cam sensor , crank sensor, ECM, on a 1992 buick lasbre 3800 and car will not start. Sound like timing is off!

dont replace anymore til u know the cause--test for spark 1st-it may just be the ignition module--a worn coil--or bad distributer cap--battery cud be too weak and old-or alternator is------fuel pressure may be weak---------aftermarket electrics dont always work well either--a diagnostic scan can help at a privateshop

2003 Buick Lesabre Battery is good and Altnator is good but is not charging the battery, I have no idea what it could be??

Chances are its the wire between the alternator and the battery, or the circuit that goes to the warning light on the dash. The warning light powers the volt regulator in the alternator which "turns on" the alternator.
The wire between the alternator and the battery is designed to burn and cut the connection much like a fuse.
You may have to get a shop manual or repair book to get the wiring diagram needed to troubleshoot the circuits.

Not getting charge out of alternator and it is good alternator wiring seems to be in good shape what else could cause problem relays how can you tell if good

If you're not reading a charge(13+ volts)at the battery, but you have voltage output from the alternator. There are 2 fuseable links, 1 is in line with the red battery wire from the stud on the
alternator to the starter. This link can be bypassed by running a wire from the alt. stud to the pos+
post on the battery. The other fusable link is in line with the red stator wire from the regulator plug.
Check these links and repair or replace if needed. Hope this helps.

What controlls fuel air mix on 1992 buick lesabre 3800

engine control module reads airflow sensor, pressure, rpms, etc. and calculates fuel charge for injection. In some cases, the ECM may use O2 sensor data to modify fuel charge. Does this answer your question?
