Grid Heater??
#5
On a Non-intercooled '91 the "timer" is on the firewall, near the column.
On a '91.5 (Intercooled) it's behind the battery in the fender.
There are several reasons the grid heaters won't activate and a bad timer is only 1.
You could have a bad air temp sensor or bad wiring connections from the timer to the solenoids.
Troubleshoot it like you would anything else, verify that each peripheral component works, such as the solenoids and the grid heating elements.
