What does my check engine light trouble code $7e8 mean?
That is what they call a "generic" code. Some OBD11 or OBD2, "same thing", scanners will give a $7E8 and $7EA. together and maybe a $7E9.
These are for a sub menu. Click on each one separately and you should or might get a regular "P0" code if your scanner
has the supported module. If not either get a better scanner or
go to a "big box" auto parts store and they will scan it for free and
should be able to give you more information.
Please comment or feedback if helpful.

Which fuse works the windows for the 02 aztek
Doesn't have fuse for power windows . Has circuit breaker ,
System circuit breaker (POWER WDWS Circuit Breaker 30A )
Those rarely go bad .
Power Windows System Components
The power window system consists of the following components:
• Window master switch
• Front passenger window switch
• LR window switch
• RR window switch
• Window motors in each of the doors
• System circuit breaker (POWER WDWS Circuit Breaker 30A)
Power Windows System Controls
The power windows system can be controlled by a power window up or down switch activation.
Driver Window Operation
When the ignition switch is in the RUN or ACCY position, or retained accessory power (RAP) is enabled and the window master switch is activated to the DOWN position, battery positive voltage is applied to the window motor causing the window to open. When the window master switch is activated to the UP position, battery positive voltage is applied to the window motor in the opposite direction and the window closes.
The window master switch also controls the front passenger, LR, and RR windows.
Express Down Feature
The driver window will travel to the fully down position when the window master switch is pressed past the first detent. Activating the window master switch to the UP position will cancel the express down feature.
Lockout Switch Feature
The window master switch has a lockout switch which disconnects the battery positive voltage to the LR and RR window switches, disabling them.
Individual Window Operation
When the ignition switch is in the RUN or ACCY position, or RAP is enabled and an individual window switch is activated to the DOWN position, battery positive voltage is applied to the window motor causing that window to open. When the individual window switch is activated to the UP position, battery positive voltage is applied to the window motor in the opposite direction causing that window to close.
The only way to find the problem would be to view wiring diagrams an test the electrical circuits with a volt meter .
