Common 1986 Chevrolet Monte carlo problems

The Chevrolet Monte Carlo, particularly the 1986 model, is known for several common problems that owners have reported over the years. These issues range from electrical problems to mechanical faults, and some can be quite serious if not addressed promptly.

Electrical Problems: Many Monte Carlo owners have reported various electrical problems, such as malfunctioning turn signals, non-functioning tail lights, side marker lights, and dash lights, as well as issues with the temperature gauge and heated seats. These problems can be caused by faulty wiring, blown fuses, or malfunctioning switches.

Broken Coolant Elbows: This is a common problem in the 1986 Monte Carlo, particularly in the L36 engine. Broken coolant elbows can cause coolant to leak, leading to overheating and potential engine damage. Prevention involves replacing the elbows anytime they are taken off, as they frequently break.

Bad Blower Motor Resistor: This issue affects 2000-2003 Impala and Monte Carlo models, causing the climate control to only work on certain settings. Replacing the blower motor resistor is the solution to this problem.

Bad Multifunction Switch (MFS): This problem can cause the lights to malfunction, and while temporarily jiggling the MFS can provide a temporary solution, replacing the MFS is the permanent solution. Prevention is not possible for this issue.

Windshield Wipers Not Parking Properly: This issue can be caused by a small metal tab on the wiper transmission that gets bent out of place. Straightening this tab out can solve the problem.

These are just some of the common problems reported by Chevrolet Monte Carlo owners. It is essential to address these issues promptly to avoid more severe damage to the vehicle. Regular maintenance and inspections can also help prevent these problems from occurring in the first place.

POWER TRAIN PROBLEM

Date Of Incident: 1998-10-01
VIN: 1G1GZ37G1GR
Components: POWER TRAIN
Summary: TRANSMISSION FAILS TO COME OUT OF LOCK UP CAUSING CAR TO STALL AND SHIFT ERRATICALLY WHEN RESTARTED. I FAILURE ANALIZED THE PSOLENOID WHICH WAS REMOVED AND FOUND THE MAL-FUNCTION TO BE CAUSED BY A BLISTERING OF THE PHENALIC CORE MATERIAL DUE TO OVERHEATING THUS CAUSING THE SOLENOID PISTON TO STICK OPEN AND NOT ALLOWING THE FEFLOW OF FLUID TO THE PROPER NON LOCK UP AREAS. I AM NOT ALONE .... THIS IS A FACTORY DESIGN DEFECT IN THE 400 TRANSMISSION. MY SOLUTION WAS TO DECREASE THE POWER ACROSS THE SOLENOID BY 20% BY ADDING A 4 OHM 1 WATT RESISTOR IN THE POWER FEED CIRCUITRY FROM THE NORMALLY CLOSED BRAKE SWITCH POWER FEED. ACTUALLY , GM HAS AN INCORRECT DESIGN HERE AND PERHAPS SHOULD HAVE USED A TEFLON CORE MATERIAL WHICH WOULD NOT HAVE BLISTERED OR HAD A DIFFERENT POWER TYPE UNIT WHICH WOULD NOT HAVE BEEN DEGRADED BY THE HEAT. PROBABLY NOT MANY 96'S AROUND BUT AT OVER A HUNDRED BUCKS A FIX AND POSSIBLE ACCIDENTS .... YOU MIGHT LOOK INTO. THANKS
