A/C compressor on a 1998 Ford Explorer XLT 5.0 V8 not engaging.

It will be the large pipe from the fire wall to the compressor, usually closer to the compressor.

I don't mean to rain on your parade, but you do not have an idle cable. You have an IAC valve. That's assuming you have the 4.0 v6. The XLT and one version of the Eddie Bauer package came with the v8.

I don't list a map sensor for that model.
I do list a MASS sensor which measures air flow between the air filter and the throttle body.

i dont think the blend door pumps are electronic rather work with vacum so my best bet is to check that ure blend door aint broken best way u should hear a bump when u turn cold hot knob from end to end, and that ure main vac line on the engine compartment aint broken and even if electronically control that should be ure second step

it may not be the belt that is the problem it could be the A/C clutch that is squealing or the A/C compressor unit cheers.

ok you can take the egr valve off and clean it and if that works you my need to take it to get reset on codes other then that also check vacum lines if these do not work you will have to replace and i hate saying that because this part is high.. good luck to you and have a blessed day..

the front axle bearing could be shot. This is common. Also the hubs may not be locking which is even more common

make sure all the wires were connected back to the battery there is a red wire that sits by itself and when you disconnect the battery it tends to fall also check the alternator circuit breaker could be blown.

I had a prolem with my 1998 Ford Explorer XLT. The 4wd indicator light would randomly start to blink while moving and when I flipped the switch to 4wd hi or low it would engage but easily disengage and the indicator lights would not come on. I was hearing a grinding sound coming from my hubs so I replaced both front hub assemblies and the light stopped blinking and 4wd hi/low works great now. it was about 300 bucks for the hub assemblies and only took me an hour or two to change.
