1997 GMC Sonoma Problems

Heater Core Under Right Side of Dashboard May Leak Engine Coolant

The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.

Power Window Motors May Fail From Overheating

A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.

Check Engine Light With Code P1870

Vehicles equipped whit a 4 speed automatic transmission may develop a harsh 1-2 shift and/or illumination of the Check Engine Light with code P1870 stored. This can be caused by wear of the bore for the TCC isolator and regulator valves in the valve body. This condition does not commonly occur until the transmission reaches normal operating temperature. If the valve body is worn, replacement will be necessary to correct this concern.

Bought 1997 Sonoma with 4.3 V6 and 5 speed Trans with 36000 miles on her. Since then I have 0ver 373000 miles on her as of today. She's one tough truck. Since New I have replaced 1 water pump, 1 fuel pump, 1 intake gasket. Believe it or not. I,m still on the original clutch, though She starting to chirp once in a while now. So my baby letting me know its getting to be time for replacement. I'm ...
I have a 97 gmc sonoma and it stalls out at times while driving. the mechanic can't find the reason for it happening. He thought it was the module so he changed it but it stalled out again. I suggested that it might be the fuel filter but he said that was not possible. Any suggestions?
one of the reasons why a fuel pump goes bad is lack of changeing the filter and the pump has to work harder to push the fuel through the system
